Pale Moon 27.7.0 is a new version of the web browser that was released on January 15, 2018. The latest version introduces new features as well as stability, security, and privacy improvements.

Pale Moon shares a lot of code with Mozilla Firefox, but there are fundamental changes between both browsers. These differences were catapulted to a new level when Mozilla announced that it would cut legacy features from Firefox.

The development team of the web browser shared its vision for the browser's future in early 2017. The decision was made back then to support Firefox legacy features such as the legacy add-on system or plugins, and to start work on a new browser project that goes under the codename Basilisk.

Basilisk may become the source for a future version of Pale Moon, but it is a separate project right now. The first version of Basilisk Browser is available already.

Pale Moon 27.7.0

Pale Moon 27.7.0 is available for download on the official project website and through the browser's automatic updating mechanics. You run a manual check for updates with a click on Pale Moon > Help > About Pale Moon. Updates are downloaded and installed automatically when discovered.

The Pale moon release notes list all changes that went into the version. Pale Moon 27.7.0 includes several significant privacy and security changes. The browser won't fill out log-in details anymore by default to reduce risks of them being stolen or abused for tracking purposes.

Pale Moon users find a new setting under Preferences > Security called "Automatically fill in log-in details" which they may use to enable the auto-fill functionality again.

The new Pale Moon version comes with additional privacy improvements. It features a new configuration parameter to disable the visibility Web API to block sites from finding out whether they are actively displayed to the user.

Load the address about:config?filter=dom.visibilityAPI.enabled to manage the new preference. A value of true means that the API is enabled, a value of false that it is disabled.

The developers disabled the sending of referrer information when links are opened in new private windows as well in the new version.

Pale Moon users who used the "ask every time" cookie policy will notice that it is not available anymore. The team suggests using extensions that control the setting of cookies instead.

Pale Moon 27.7.0 includes the performance timer changes that prevent Spectre attacks against the browser. Mozilla implemented the changes earlier this month in the Firefox browser as well.

Other changes

Most of the remaining modifications fix issues in the browser or re-organize things. Linux users find Preferences under Tools in the new version, and the "restart with add-ons disabled" option was renamed to "restart in Safe Mode."

The new version fixed a crash issue, updated the SQLite library, and fixed lots of bugs besides that. I suggest you check out the official release notes for a full rundown on what changed in the new version.

Now You: Which web browser do you use predominantly nowadays?

Pale Moon 27.7.1

Pale Moon 27.7.1 was released on January 18, 2017. It is a bug fix release that addresses two issues. The first completes the implementation of Javascript's ES6 Unscopables which caused some sites to display blank or load incorrectly.

The second resolves a too thick tab borders issue in Windows systems that used higher settings for element scaling.

    Ahem! v27.9 is out now. Apparently there are video fixes now (I wonder if those are for H.264 issues)
    New Moon is a custom build by Roytam1 is MSFN, and his build uses LAV filters to play these files on XP and Vista. I personally don’t care about the XP part, but it’s nice to have a working x64 browser on my Vista machine.

  2. Jody Thornton said on March 5, 2018 at 2:37 am

    I find it rather surprising that given how Pale Moon is to be “Your Browser – Your Way”, that there have been a number of threads lately where Moon-Matt have both been advising against the use of about:config too much.. I understand the concern about messing up settings, but this is appears to a new trend appearing from the Moon-Matt collective mind. Tinkering used to be encouraged.

    Notice again to all of those that say I dig unfairly against the crew at Pale Moon: look how unhelpful Moonchild and Matt Tobin are towards the fella asking for help. Instead of pointing out to him what he might be able to do, they tell him why it can’t be done. It used to be the case, that people on that forum were encouraged to try what worked best for them.

    Maybe Moonchild sees a weary future ahead and is trying to spare himself some grief.

    Don’t know about others but after upgrading to the new PM release, I seem to have lost all my saved ID’s + passwords and have to reenter them as I revisit sites.

    Very annoying!

    1. Kubrick said on January 17, 2018 at 2:44 pm

      what is annoying is people who will not read the entire release notes when the new version was released,if you had of done so then you would of realised this was by design as a security measure.

      “fools rush in where angels fear to tread.”

      1. Jojo said on January 17, 2018 at 7:44 pm

        I have better things to do than to get buried in the minutia of PM new release details.

      2. Jody Thornton said on March 2, 2018 at 11:41 pm

        Oh well, v27.8 is out now

    2. Jody Thornton said on January 17, 2018 at 1:17 pm

      Again, go to Preferences -> Security, and then click “Automatically fill in logon details (halfway down you’ll see it).

      He’s disabled the default filling in of passwords as a security measure (he being Moonchild, of course)

    I switch between Pale Moon and Firefox 56.0. I can’t complain about Pale Moon, but I do stay away from the forum. Back when Start Page was new, it did something weird every time I opened the browser. I couldn’t get off the page and it ate 50% – 70% CPU. When I asked how to avoid that, I was told to stop complaining and use a different browser. So I did. When, a year later, I tried Pale Moon again, the problem had been resolved.

    I haven’t tried Vivaldi, and much as I loved the old Opera, I won’t use it again. As I recall, it was first to dump support of XP. I am staying with Win7 and so believe Pale Moon is my best bet.

    1. jojo said on January 17, 2018 at 7:03 am

      I got thrown out of the PM forum by the top ahole himself because after a couple on years on there, he decided that he didn’t like my disposable email address.

  5. James Cheatham said on January 16, 2018 at 10:27 am

    I use a combo of Vivaldi, Pale Moon and Opera. I like Pale Moon, I love the privacy and security work the team are doing. There are a couple of things I kind of wish they’d build into the browser, but I can’t complain, it’s a stable browser and a fine piece of software to use.

    was a supporter of palemoon for years (including hosting files) but have just (since I run windows and linux mint) had much better luck with waterfox over last 2 years.
    but whatever, I wish palemoon devs the best and hope it works well for them and the users.
    it is a browser worth checking out.

  8. Kubrick said on January 15, 2018 at 8:06 pm

    To be honest i am rather sympathetic to moonchilds efforts and i feel pity for him having to cater for so many silver platters all the time.Palemoon is what it is and should be accepted for that.

    It is doing no good moaning and bitching about it….If you dont like the browser then simply dont use it.
    Maybe more people should consider contributing to the project rather than complaining.

  9. Foxtro said on January 15, 2018 at 7:13 pm

    Pale Moon was my default browser before…but now is backup browser to Waterfox, right now the best browser imo. Modern, fast, configurable…no issues and glitches as on Pale Moon.

    Let me clear first, Pale Moon is a good browser. Good, but…not enough. “Customation and Security” are probably good arguments for “average Joe”, I think.

    And I agree with Jody Thornton and Appster, Pale Moon forum is poisoned… a sketchy project for my taste. To mention from top off piramide to down to the fanboys…a lot off strange atitudes, a lot off egoes , begine from “Moonchild, aka Guru, aka van Gogh” and “Thobin, aka Paradigme, aka Mediocre”.

    I think that is shame, a lot off nice and skilled people there are on forum anyway.

    If Alex and his people from Waterfox could find some “interest” and join force with some people from Pale Moon (my preferable choises: Satrow, JustOff, Travis)…it could bee the best browser ever.

    Thanks Martin for this site, wich I follow almost from begining!

  10. Mark Hazard said on January 15, 2018 at 6:53 pm

    Thanks for the article Martin. I had tried to install Pale Moon for Linux before, but was unsuccessful.
    I tried again today to install the latest version, and was successful, using pm installer.
    When I launched it, I found that it came with much baggage that I did not want, and was either unable to get rid of it, or that I was too lazy to make a lot of unnecessary changes to it.
    So I uninstalled it, using pm installer.
    I like to have my browsers MY way. I still have four browsers on Linux.
    Still, I appreciate that you keep us current with all the latest technology.

  11. Gerard said on January 15, 2018 at 6:52 pm

    No update of the Linux build at the time of writing:
    “Latest version: 27.6.2”
    ( )
    The Pale Moon for Linux installer reports that I already have the most recent version (27.6.2).

    Why, I wonder.

    1. Kubrick said on January 15, 2018 at 8:02 pm

      you need to wait until travis builds the linux version for release.he usually releases the linux version the same day as the windows version.

      Patience is a virtue.

  12. That PM moderator forum said on January 15, 2018 at 6:29 pm

    I need to say that lately some guy enter in the forum of Pale Moon and said in a post “when you will gay out your users?” literally. I am sorry but that is not a bug report or feature request, not a polite debate or else. That was a troll trying to provoke us. If you dont like the project, just use another one as you are not “married” with a browser. I myself use like 3 for made work done. We are volunteers trying to have a browser that Mozilla should delibered but broke for things like Australis. Finally I think that the XP version of Pale Moon is a great idea but some devs dislike it just because they dont want to mess their hands in that OS. – My 0.02 and I wont come here to see replies, this was just an off the record comment.

    1. Jody Thornton said on January 15, 2018 at 7:35 pm

      I agree a comment like the one you saw is completely unacceptable, and more importantly, hurtful

  13. kubrick said on January 15, 2018 at 5:33 pm

    Brace yourselves ghacks.
    the anti-palemoon squad is amongst us.

    i use palemoon and its a great browser and its about the only one that allows full themes just like the old firefox.
    Even firefox does not allow full customisation.

    Let the palemoon debate begin.

    1. Appster said on January 15, 2018 at 8:29 pm

      Nope, not gonna thoroughly comment on a browser that isn’t even capable of running most modern add-ons and has rather bad web standard support. Its weak points are self-explanatory for anyone who cares to do some research.

    2. Jody Thornton said on January 15, 2018 at 5:39 pm

      No Kubrick. I’m not going to say anything further, and I’ve already stated that. I also use Pale Moon for now. That will change, but not for now. Nothing negative to say.

  14. Anonymous said on January 15, 2018 at 5:09 pm

    Switched back to the 27.6.2, this new release don’t want to show my passwords in the boxes.

    1. Richard Allen said on January 15, 2018 at 9:25 pm

      Can’t you click in the text area to bring up your log-in options? I have “Automatically fill in log-in details” unchecked and can still see my usernames and passwords, after a click. All of my FF based browsers have been setup to work that way, including Pale Moon before this update.

      1. Anonymous said on January 15, 2018 at 10:24 pm

        …and to answer to your question more precisely, with “Automatically fill in log-in details” unchecked, no option at all when I click on the text area.

      2. Anonymous said on January 15, 2018 at 10:09 pm

        Thanks for your advice. However for each site with password (only few) I use, I have a dedicated Pale Moon portable “installed”.

    2. Jody Thornton said on January 15, 2018 at 7:34 pm

      Go to Preferences -> Security, and then click “Automatically fill in logon details (halfway down you’ll see it)

      1. Anonymous said on January 15, 2018 at 8:48 pm

        Yes I just saw my incompetence on the subject, thanks. No release notes in my language and sometimes always being forced to read/write english tires me, sorry for that.

  15. Jody Thornton said on January 15, 2018 at 5:05 pm

    Some differences that I noticed. A couple of saved passwords aren’t retrieved. But more noticeable is the change of the menu item for “Options”. It’s now akin to the Linux build and says “Preferences”.

    1. Jody Thornton said on January 15, 2018 at 5:11 pm

      Let me add to that. The reason the password did not show up was that “Automatically Fillling in the Password” is disabled by default.

    I tried Basilisk but I was not capable to install uMatrix 1.1.4 like on Pale Moon. For me Pale Moon is still the best at this time.

    1. Jody Thornton said on January 15, 2018 at 5:02 pm

      Is it a WebExtension or a legacy one?

      1. Anonymous said on January 16, 2018 at 7:47 am

        uMatrix.webext.xpi 1.1.4, “not compatible” the browser said.

      2. chromeFOX said on January 16, 2018 at 3:40 am

        You must be late on the up keep when Gorhill pulled out support for Gecko version of uMatrix add-on to primarily make it a full blown chrome WebExtension.

  17. Jody Thornton said on January 15, 2018 at 4:12 pm

    Also, I received a lot of flack in previous Pale Moon related posts for acting trollish. I was told I was being slanderous/libelous for accusing the Pale Moon team and members of horrible behaviour.

    Well just in the last few days, Matt showed himself for what he is. If you cannot agree that he acts arrogant and dismissive to the folks trying to fork an XP version of Pale Moon, then I don’t know what to say.

    I will leave it at that. I have made a New Years’ resolution to calm my nerves down when I see stuff that angers me.

    1. Ray said on January 15, 2018 at 7:17 pm

      New Tobin Paradigm is absolutely bonkers.

      If he bothered looking at the Pale Moon XP forks, he would see that roytam1 renamed his Pale Moon XP build to “New Moon.” The Basilisk XP build hasn’t been renamed yet though.

    2. Earl said on January 15, 2018 at 5:24 pm

      What I don’t get is how they can call Pale Moon “modern” [looking] when it still looks like Firefox 4, which I liked fine… way back then (7+ years ago). I liked the Australis Developer Edition way better–was much easier to mod as well. It’s all the same to me.

      1. Weilan said on January 15, 2018 at 6:43 pm

        It’s not about how it looks, but what it does. Sadly Pale Moon doesn’t excel at anything. I like how it looks, because of the old school feel, but the lack of proper modern day web support makes it unusable for me.

    3. Appster said on January 15, 2018 at 5:18 pm

      Sadly, that’s a primary example of how the main Pale Moon devs usually behave. However, Jody, if and when we criticize Pale Moon, we should resort to comments on product features, as they are the reason for our criticism in the first place. We shouldn‘t overdo our opinion on the team. It is what it is. They won‘t change because of us. If some people are willing to join their board in spite of their attitude, then fine. It’s their decision to pit up with them. The facts are more important anyway.

      1. Lexxxian said on January 18, 2018 at 12:29 pm

        No matter how much you bash or flame about PM – Me and many users will not stop using it @Appster.

        Guess that must make you mad like hell :D Many of us PM users couldn’t care less about Webstandards because we have a secondary browser for pages which don’t work.

        Go play with your Google controlled toybox of choice, we do not want or need that. And PM is more than enough for simple and normal pages. So, even weak webstandards support is no issue at all.

        People who constantly use the latest shinies drafts wise instead of normal reasonable standards also can be hardly called webdesigners.

        Steve Jobs was not the easiest guy to deal with either, however he was pretty successful – Pixar, Apple, etc

      3. Tom Hawack said on January 15, 2018 at 5:48 pm

        I totally agree with you, Appster, mainly with the fact of resorting to the product’s features, leaving behind personal opinions.

        I’d add that if we are to deplore a product’s feature and if we know that such negative critics are likely to trigger a dev’s excessively tough reaction (which in turn may induce ours), a rather perfidious, hypocritical (some say “diplomatic”) way is to defend the product’s feature by emphasizing on critics (which we firmly condemn of course!) which devalue it. “How dare they say that [this] and/or [that] is archaic, badly brought out [etc] when in fact it’s so brilliant….”.

      4. Jody Thornton said on January 15, 2018 at 5:22 pm

        That’s true enough.

        Happy belated New Year Appster!

    Martin, not sure if you noticed but they also mentioned that their integration with the Mozilla add-ons site is being removed in a few months.

      Thanks, I did not know that!
