Which Firefox extensions would you like to see promoted by Mozilla?
Mozilla announced the Recommended Extensions program for Firefox on April 9, 2019 designed to promote excellent extensions for Firefox in various ways.
Extensions need to meet the "highest standards of security, utility, and user experience", be in active development, safe, offer exceptional user experience, and be really good at what they do.
The program goes beyond the featured extensions listing that Mozilla uses currently on the official repository for add-ons.
Recommended extensions will be reviewed by human reviewers before they are accepted in the program, and then each time an update is released. Human reviews reduce risks associated with automatic review systems significantly; it would look really bad if Mozilla would recommend and promote an extension that would do something shady.
Mozilla plans to promote the extensions in several ways, e.g. on the official Add-ons repository and through the contextual extension recommendation feature of the Firefox browser.
Mozilla mentioned that it contacted several developers already but did not mention names or specific add-ons that it considers for the program.
Popularity may play a role in the initial selection phase but it is likely that popularity -- user counts and ratings -- are not the only factors. If an extension is well designed and exceptional, it is probably a candidate even if the user count is low in comparison.
Tip: A good starting point is our best of Firefox add-ons listing.
Mozilla and the extension developer both need to be willing to accept an extension in the Recommended Extensions program.
Which extensions will likely be included?
Mozilla's Firefox Add-ons website list 15095 extensions for Firefox. Which of these will be included in the program?
If you look at the most popular extensions, you will find several likely candidates. Content blockers and security extensions like Adblock Plus, uBlock Origin, or NoScript are likely candidates. Productivity tools, Video DownloadHelper, EasyScreenshot, Enhancer for YouTube or LastPass may also be included.
Some top rated extensions, even though some may have less than ten thousand or even less than a thousand users, may be candidates as well. Extensions such as SingleFile, Panorama Tab Groups, or Vimium-FF are potential candidates.
Closing Words
If you ask me, I'd like to see a good mix of popular extensions and lesser known but highly polished extensions added to the recommendation program. It would not make much sense to just look at user numbers and base the decision solely on that as it would reduce the discovery aspect of the recommendations.
Remember the time when barely a week passed by without a new cool Firefox extension release that added something unique to the browser or sites you visited? Some of that magic would certainly be useful.
Now You: Which extensions would you like to see added to the program and why?
Save my Password
https://addons.mozilla.org/en-US/firefox/addon/save-my-password/
a very simple addon, but fixes a huge PITA with sites that don’t let you save passwords. (this should be built into Firefox really)
I use the following all the time. Nothing exciting for geeky peeps.
Still lamenting the loss of pre-WebExtensions Tab Mix Plus. I also use Pin4Ever to back up Pinterest, which still works in Waterfox etc. and I’ve managed to force Firefox (sometimes grrrrrr) to remain on Ver. 56 (on a dedicated laptop) to continue using it.
I also still use the now sadly gone Save Button for Pinterest, which allows images to be pinned from Facebook, which is otherwise not allowed (WTF for, who knows). There’s always screen cap, of course.

The Chrome Store.
Do I recall ??? way back, that Mozilla claimed Quantum would be compatible with Chrome Extensions….???
Stan. Quantum is “compatible” with Chrome extensions. You pretty much have to replace “Chrome” with “Browser” (in the code). Pre-Quantum Firefox could use the Chrome Web Store, Chrome extensions, WebExtensions AND more because it had a very capable add-on system. Of course that wasn’t possible by default and I doubt they would allow Chrome Web Store support by default.
A great pick would be Dissenter. Or did Mozilla remove it already?
I don’t know anything about Dissenter but hate speech isn’t okay.
You don’t know anything about Dissenter, but, managed to connect it to “hate speech” … smells fishy.
“I hate my job!” Ooops, that’s Hate Speech, you’re banned!
YOU’RE not OK, DragoCubed. The First Amendment exists to protect speech that is offensive. When you grant an authority to ban “hate speech” they will unfailingly use it to censor any views that interfere with their power and agenda.
And the bravely-named Anonymous is just as deluded. Censorship is wrong, found most common in main street media and on college campuses, and it is ALL from the left.
What does Dissenter have to do with hate speech?
Beside that, either you support or oppose free speech, there is no in-between.
Dissenter is a commenting addon launched by the far-right extremist social network Gab:
https://en.wikipedia.org/wiki/Gab_(social_network)
“On February 24, 2019,[29] Gab launched a browser extension and website called Dissenter, which allows users of Gab to make comments”
“Gab is an English-language social media website that is known for its mainly far-right user base.[8] The site has been described as “extremist friendly”[9] or a “safe haven”[10] for neo-Nazis, white supremacists, and the alt-right.[9]”
“It has stated that conservative, libertarian, nationalist and populist internet users were its target markets.”
The funny thing about them pretending to support free speech is that, ideologically, the far right is the first supporter of
* arbitrary censorship of anyone by private companies (for example they are against net neutrality because it would prevent private ISP from censoring whatever they want), that’s their “libertarian” face
* censorship of anything left-wing by everyone, of course, that’s their fascist face

I look in categories or for something mentioned here or elsewhere. I’m willing to look at promoted extensions if they have some special merit and don’t pop up unexpectedly interrupting browsing. Oherwise the term “promoted” is a turn off; I’ve tried recommended extensions and have never found any I keep for long.

I think that CanvasBlocker now includes a window.opener protection that makes the Don’t touch my tabs! extension redundant now.
The ones that finally convince you to abandon Firefox and switch to Palemoon.
Dissenter meets all the criteria.
Mozilla has censored Dissenter: https://www.oneangrygamer.net/2019/04/dissenter-extension-removed-from-firefox-add-ons-gallery-for-abuse/81954/
Yep. Gave up on Firefox and went to Brave. Things got on a downward spiral the moment they fired Brendan Eich. Now they try to mimic Google in everything they do without people complaining too much about cloning their Chrome browser.
What is hate speech anyway? It’s just a concept used to illustrate speech some people don’t like and is in opposition to the freedom of speech, an ideal which Mozilla has now in name only. They and hypocrites and no longer fight for an open internet.
Featured, promoted or whatever label doesn’t interest me at all. I rely only on the extension’s description, the developer (other extensions, homepage) and of course on users’ comments, when comment there is and when the comment is documented, be it good or bad. The ratings, especially those with no associated comment, are IMO insignificant, I even believe the rating concept is basically stupid, an incentive for empty brains to consider a rating star as the expression of their empty brains (logical by the way).
So: an extension’s description, its developer and users’ feedback are the only points I consider. Remaining “product of the week/year” and of the sort remind me too much of the ads business to give these flags a whatever merit.
I’d wish that human reviews be a general practice for all extensions proposed on an extensions’ store. If we have to consider an extension as eminent on that ground we’re likely to bring a ‘promoted’ label as the guarantee of a good extension. Just have Mozilla guarantee that extensions on AMO are clean and let the users exercise their interest independently of labels and number of users of that extension, the latter an absurdity of modern times when we all know that masses don’t express truth.

I agree with your values.
Values and preferences are diverse. Of course, use of PC purpose, even how to use the Browser is the variety.
I am not interested in digital contents such as SNS (Facebook, Twitter), GAME, You Tube.
With internet connection, the most important thing is privacy protection (fingerprinting measures). Its management must be controllable by the end user.
For this reason, I need the ability to control the connection with the vendor (For-profit companies such as Google and Facebook etc) that I want to ignore.
The Internet connection uses “Nord VPN”, and the connection management uses “simplewall” and “WPD”.
Browser’s favorites are Tor Browser, Firefox Developer Edition, Brave Dev and Pale Moon. Of course, config is also customized (fingerprinting measures).
In short,
My choice is not “one and only”, but rather a “favorite” as a result of personal preference.
Based on them,
Firefox-extensions that I have implemented at the moment are as follows.
However, no extensions have been added to Tor Browser.

It might be interesting to see statistical distribution of empty comments and number of stars.
@Tom Hawack: why is the rating concept “an incentive for empty brains to consider a rating star as the expression of their empty brains”?
If someone is happy or unhappy with an extension and expresses that sentiment with 1-5 stars, what is “stupid” about that? To me, rejecting others’ opinions, even if those opinions are from non-tech users, is rather narrow-minded.
And if you look at it, a good extension will overwhelmingly receive a high number of stars, with the odd low star rating representing a numbskull or someone who did something wrong and is probably too lazy to do something about it. The opposite applies to a bad extension.
@Klaas Vaak,
> why is the rating concept “an incentive for empty brains to consider a rating star as the expression of their empty brains�
> To me, rejecting others’ opinions, even if those opinions are from non-tech users, is rather narrow-minded.
My point is to emphasize on the value of opinions, which is why I pointed out the importance I attach to users’ feedback. But an opinion expressed with only a scoring is not an opinion. Whatever the user’s skills, he/she has to explain the reasons of the rating, otherwise it’s meaningless, IMO of course. “I like it, a bit, a lot, not at all” is an emotion, not a description. Why do I like it, a bit, a lot, not at all is the invitation to a constructive comment, dialog and only then authorizes a scoring meant to express the comment, as I see it of course. It’s too easy just to score without explaining why and again, IMO, an incentive to call upon users’ emotions rather than reasoning. This said, we also notice once in a while extension developers who give no, or quasi no description of their add-on. So it’s less a matter of technical skills than of respect for others.
@Tom Hawack: you are contradicting yourself a bit. You state rating is for empty brains, but you go on to state that a rating with a explanation is useful. In other words, rating per se is NOT stupid or for empty brains, but it is reduced to a meaningless exercise when not accompanied by an explanation.
Another point is emotions. Being a rational person myself (most of the time) I prefer a rationally argued case too. But it is alo possible to give a purely emotional feeling that can be of value. For example, most people will agree, me included, that a BMW is a high quality car, but there are those, me included, who just don’t like them. Is my opinion less valuable than yours with a well argued explanation? Ça se discute.
@Klaas,
> “For example, most people will agree, me included, that a BMW is a high quality car, but there are those, me included, who just don’t like them. Is my opinion less valuable than yours with a well argued explanation? Ça se discute”
That’s a reason to emphasize on commenting rather than on rating : what do you rate, the quality of a BMW or your personal interest for the car? How is a reader to know what your rating applies to? But if you write, i.e. “BMW is high quality but personally I don’t like it”, if, better even if you say why you dislike it and end your comment by stating, i.e. “5 for the quality, 1 for my interest, hence an average 3 stars” … then everyone understans your position, ex-pli-cit-ly!
@Klaas Vaak, I never wrote that rating is for empty brains but that “the rating concept is basically stupid, an incentive for empty brains to consider a rating star as the expression of their empty brains (logical by the way).”, in other words that it is stupid in its incentive to allow empty brains to use it in place of a comment. It’s not the same thing, which is why I developed my argument in my second comment. I neither said as well that rating was useful. I implicitly stated that rating’s only pertinence was when it sort of summarized a documented comment, and I nuanced this for the sake of intellectual honesty because frankly, between you and I, I remain convinced ratings, with or without comments, remain a basic stupidity which bring nothing to readers.
I don’t believe, as you write it, that “it is also possible a purely emotional feeling that can be of value”. Not that its not possible : it’s feasible and not forbidden! but that an extension is not a piece of art, you don’t install it for the pleasure of your soul but to use it, emotion is irrelevant here. Sensitivity and sentimentality are two different things and the latter is concerned when a user rates with no rational reason, at least expressed. But this is the big stuff nowadays : “vote, even if you don’t know why, just let your heart speak”. Your heart or your guts because if you list ratings free of comments they are mainly 1, 2 start ratings. If one must say why he dislikes and rates 1 start accordingly same applies to why he likes : in the former case there may be irelevant hatred, in the latter fake ratings (friends of the developer who were in a hurry). I repeat that, IMHO, ratings are stupid and that what is beneficial for all, the speaker as well as the audience is less an approximate rating than words, words, sentences, the meaning. Simple, no?
@Tom Hawack: “I never wrote that rating is for empty brains but that “the rating concept is basically stupid, an incentive for empty brains….”
If the rating concept is stupid, then, logically, the rating that flows from it is stupid and for empty brains too. In fact, you even confirm it, stating: “I repeat that, IMHO, ratings are stupid …”
So, you are trying to prove that I misread/misunderstood your words, and yet you confirm my reading of them. Duh …
No, an extension is not a piece of art, although some people may not agree on that, but neither is a BMW. Yet, both an extension and a BMW generate emotions, feelings, which are subjective by definition. Yes, a rating with an explanation is a lot more valuable than one without, there is no doubt about it. Those without you can ignore, those with you can take on board in your considerations. In my modest opinion, if an extension has a lot of likes, even if there are many unexplained ones, there is a good possibility that there is something good about the extension, or in any case it warrants further investigation rather than outright rejection. Simple, no?
Nano Adblocker
https://github.com/LiCybora/NanoCoreFirefox
These days it has to be ad/privacy ones at the top of the recommendations. So for me ublock origin, decentraleyes and privacy possum and something like cookie autodelete and quick js switcher. Anything else other than a password manager of your choice are just nice to have but those are must haves.
LastPass, uBlock Origin and Vimium are essentials for me in any browser I use regularly.
I always add Zoom Page WE, smartUp Gestures (adding both dragging and mouse gestures) and Checker Plus For GMail to any browser for which they are available.
I also like an option to suspend tabs, and Discard@Dook is my preference in Firefox…I like it better than other tab suspenders, including The Great Suspender which I use in Vivaldi.

I see you’re still recommending Ghostery on your ghacks.net best addons page. From their english privacy policy :
“Offers, also known as Ghostery Rewards, is turned on by default and allows companies to show relevant marketing offers to users based upon an algorithm we created that anonymously determines intent and therefore particular commercial offers that may be of interest to you. ”
“we automatically collect non-private URLs, search queries along with search engine results pages, suspicious URLs that could potentially be phishing websites, information related to safe and unsafe trackers, and information related to the prevalence and performance of Trackers.”

SingleFile: It’s very helpful to archive websites. I use it very often!
Came here to write the same thing! Best Plugin for Firefox period. I never saw it mentioned anywhere else before this post.
So is Save Page WE
@tom42: agreed, and I find it better than SingleFile.
There are sites’ pages ‘Save Page WE’ won’t save correctly whilst I’ve encountered none ‘SingleFile’ couldn’t archive. Of course simple pages are easy, the difference between dedicated archive extensions appears when the page is complex in its coding. Try pages of ‘lemonde.fr’ for instance : SingleFile does the job and last time I tried ‘Save page WE’ rendering the archived html was lousy. For archiving a web page into one single html page there is at this time but one extension really valid and it’s called ‘SingleFile’. I’m surprised it is not featured on AMO which proves IMO that the ‘featured’ label is 100% baloney.
@Tom Hawack: perhaps so. I have not experienced that sort of problem, though I admit I don’t use the extension that often. What I like about “Save Page WE” is the presentation more metadata about the saved page.
In fact, I tend to bookmark pages in Zotero because saving web pages as such can end up taking up a lot of space. If I need data from a web page I will cpy and save specific parts, rather than the whole page. Sometimes, though, it is useful to have the whole page.
@Klaas Vaak:
I use them both – still in the testing phase but (fyi) one stand-out feature of SingleFile is the ability to save a portion of a page. I can highlight a section of text (and graphics) and it will only save the highlighted portion.
The right-click menu option simply says “Save Selection” but it’s identifiable as SingleFile via the icon.
I used to use both MHT (out of habit, better support among various browsers) and MAFF. Today, if I had to choose one, it would probably be MAFF since it was essentially a zip file holding the resources.
From a user-standpoint it should be a combination of the 100+- most used extensions and the 100+- technically most useful ones, irrespective of popularity.
The 100 most used extensions because they are already used by basically 90% of extension users, and thus basically the entire user base profits from Mozilla’s monitoring.
The 100 most technically useful extensions, because those developers deserve the attention and users will come in contact with new features.
Then Mozillas has around 200 extensions they need to monitor, and can ignore the other 5,000 or so, so that would be doable for a small team of security engineers.
unfortunately the second group is dead due to WE limitations

Witch one?
I use JDownloader as external download manager and FlashGot is still the best companion. I don’t know any web extension that give me the option to “save with JD” when I click on a link: by the way, “Download with JDownloader” is not the same integration. Moreover FlashGot Media still works well (and sometimes better than others). For the few things I need never had to reinstall it
If I have to do a list about why Firefox is the second browser now, an add-on like FlashGot is It’s right up there. My comment above was sarcastic, I’m not interested in any “Recommended Extensions program”, but I’m waiting API improvements. I remember a recent post when a user wrote that nearly all old add-on now can be replaced now by a similar web extension: “nearly all” sometimes makes a difference. Another examples: Theme Font Size Changer or Tile Tab.

Good extensions, but they do not support external download manager integration. I prefer to continue using FlashGot as long as I can. With the exeption of YouTube, in this case I use ‘Open With’ to quickly send videos to JDownloader or PotPlayer.
