Enhancer for YouTube for Firefox: availability, versions and privacy
Yes, Enhancer for YouTube is available for Firefox again. The add-on returned to Mozilla's official store, Firefox Add-ons (AMO), with version 2.0.131 on January 21, 2026, after the developer pulled it in August 2025. The current Firefox release is version 2.0.136 from August 2, 2026, and it requires Firefox 140 or newer. Firefox still gets the 2.x line, while Chrome runs version 3.
This page covers where to install Enhancer for YouTube in Firefox, why it vanished in 2025, how the Firefox and Chrome versions differ, what the extension does with your data, and what to do when it stops working.
Is Enhancer for YouTube available for Firefox?
Enhancer for YouTube is listed on Firefox Add-ons under the developer name Max RF, with about 601,000 users and a 4.7 out of 5 rating from more than 12,000 reviews. The developer's own Enhancer for YouTube page says the extension "can be installed on Chrome, Edge, and Firefox" and links each browser to its official store.
To install it in Firefox:
- Open the Enhancer for YouTube listing on addons.mozilla.org in Firefox.
- Click Add to Firefox and confirm the permission prompt.
- Open YouTube, then click the extension icon to set playback speed, volume, quality and layout preferences.
Install only from AMO. The listing is the version Mozilla reviewed, and it updates automatically. Copies of the extension offered on other sites are not the official build.
If you kept the old version installed through the delisting, check your version in the add-on manager (about:addons). The last release before the break was 2.0.130.1 from November 24, 2024, a rollback build that has not received YouTube fixes since. Reinstalling from AMO puts you on the current release.
Why Enhancer for YouTube disappeared from Firefox in 2025
Enhancer for YouTube left Firefox Add-ons in August 2025 because its developer delisted it, frustrated by slow manual reviews. In a statement to Ghacks at the time, Max said that a rollback release, "a pure clone of a previous version already reviewed and published on AMO", took 8 days to be reviewed, while users kept installing a build that did not work with YouTube's latest changes. He added that the Chrome Web Store and Edge Add-ons were "way more reactive", which is why he kept maintaining those versions.
Two context points from that period:
- It was not the first removal: the add-on was delisted and reinstated once before, in 2024.
- Mozilla had updated its add-on policies in June 2025, and other developers reported rejections and listing gaps around the same time.
Enhancer for YouTube was not the only extension to clash with AMO's process. The uBlock Origin developer had earlier pulled uBlock Origin Lite from Firefox Add-ons after a review dispute. For Enhancer for YouTube, the gap lasted about five months, from August 2025 to the January 2026 return.
Firefox version vs Chrome version
The Firefox and Chrome editions of Enhancer for YouTube share a name and core features but run on different version lines. The developer said in early 2025 that version 3 would come to Firefox only if Mozilla changed its review process; so far, Firefox has stayed on 2.x.
| Detail | Firefox (AMO) | Chrome (Chrome Web Store) |
|---|---|---|
| Current version | 2.0.136 (August 2, 2026) | 3.0.19 (July 15, 2026) |
| Users | About 601,000 | 1,000,000 |
| Rating | 4.7 from 12,000+ reviews | 4.5 from 17,600 ratings |
| Minimum browser | Firefox 140 | Not stated on the listing |
The 2.x branch is still actively maintained: 2026 releases added a new user interface and videos-per-row settings (2.0.132), compatibility with YouTube's experimental new player (2.0.131), and fixes for the embedded player and full-screen layout. On the Chrome Web Store, the extension carries the Featured badge.
What Enhancer for YouTube does in Firefox
Enhancer for YouTube adds playback, player and layout controls that YouTube does not offer itself. I reviewed the extension when it first came to Firefox and Chrome. The volume booster is still the standout for quiet podcasts and badly mixed videos.
The current AMO listing describes these feature groups:
- Playback: speed from 0.07x to 16x, quality and volume control with the mouse wheel or keyboard shortcuts, a volume booster up to 10x, loop mode, autoplay control and an option to disable 60fps formats.
- Appearance: video filters for brightness, contrast and color, custom themes and Cinema mode, which dims everything around the player.
- Player: a Wide Player mode that goes beyond Theater mode, plus a mini player.
- Distractions: hide end screens, info cards, recommendations, related videos, chat or comments; hide Shorts or play them like regular videos.
- Extras: screenshots and customizable keyboard shortcuts.
Ad management is no longer part of the extension: version 2.0.122 (January 2024) removed its ads features.
Enhancer for YouTube privacy and data collection
Enhancer for YouTube does not collect user data, according to its developer's declarations on both stores. On AMO, the listing states that "the developer says this extension doesn't require data collection", and the only permission requested is access to your data for www.youtube.com. On the Chrome Web Store, the developer has disclosed that it "will not collect or use your data".
The developer's privacy policy covers all of his extensions and says they "do not collect personal information", do not collect data of any sort and do not inject ads. The Google Analytics and advertising cookies mentioned on that page apply to the mrfdev.com website, not to the extension.
Keep in mind what these statements are: self-declarations by the developer, not independent audits. Enhancer for YouTube is closed source (AMO lists a proprietary license), so the code is not published for public inspection. The narrow permission, limited to youtube.com, is the strongest technical signal: the extension cannot read other sites you visit.
Enhancer for YouTube not working in Firefox
Most Enhancer for YouTube problems in Firefox come from an outdated version or a YouTube layout change that the latest release has not caught up with yet. Work through these checks:
- Open about:addons and confirm you run the current AMO version. Anything at 2.0.130.1 or older dates from before the 2025 delisting.
- Update Firefox. Current releases of the add-on require Firefox 140 or newer.
- Remove the add-on and reinstall it from AMO if updates do not arrive.
- Disable other YouTube extensions temporarily; two tools changing the same player controls can conflict.
- Check the version history on AMO to see whether a newer release already fixes the YouTube change you are seeing.
- Use the developer's how-to guide to check settings before reporting a bug.
Note the browser scope: the developer's contact page says Enhancer for YouTube is developed and tested only for Chrome, Edge and Firefox, and bug reports from other browsers will not be investigated.
Alternatives to Enhancer for YouTube for Firefox
The closest alternative is Improve YouTube, a non-profit, independently developed extension on Firefox Add-ons with more than 175 features and about 102,000 Firefox users. It covers layout, themes, default quality, playback speed, volume, Shorts and comment hiding, and keyboard shortcuts. Martin covered it in his review of Improve YouTube (then called Improved YouTube).
Choose Enhancer for YouTube if you want a focused tool with a strong volume booster and wide player; choose Improve YouTube if you want the larger feature set in one add-on. For more ideas, see our list of the best Firefox add-ons.
FAQ
Will Enhancer for YouTube version 3 come to Firefox?
There is no announcement. The developer said in early 2025 that version 3 would reach Firefox only if Mozilla changed its review process, and the Firefox listing has remained on the 2.x line since its return.
Does Enhancer for YouTube work in Brave or Opera?
It may run in other Chromium browsers, but the developer supports only Chrome, Edge and Firefox and does not investigate bug reports from other browsers.
Does Enhancer for YouTube block ads?
No. Ad management features were removed in version 2.0.122 in January 2024. Use a dedicated content blocker if you want to block ads.

Another ‘just found this comment’ comment. My version went wonky after Windows 10 support died last week but I assumed it would be a temporary situation. When I fired up my W11 Home version, it got even worse so here I am.
I’ve enjoyed an extensive, satisfying relationship with both Firefox and
Enhancer for YouTube™. Some of the bumps Ashwin endured along the way aren’t entirely lost on me. I always felt bad when he’d take a beating in comments to the point he had remove his place in the Firefox Addon catalog at temporary intervals until he resolved what was broken. It seemed to me, at the time, these where mostly issues created by YT.
Don’t get me wrong, here. I’ve been around FF long enough to recall the Cease & Desist they aimed at Pale Moon. It was kinda ugly. I saw the seriousness of the Mozilla flex during that episode. Point being, business is just business and when business ends with this kind of result, it doesn’t always end with David slaying Goliath. I have to believe these two providers of our entertainment may workout whatever is really going on.
Well, it’s been a good experience here tho I find YT fairly useless without
Enhancer for YouTube™ which chomps at a huge part of my daily internet routine. I’m hard-pressed to rationalize why FF wouldn’t bend towards keeping this Dev happy. YT TV subs are growing daily and you’d think that’s a bit shortsighted on FF’s part because this appears to be a dedicated developer with the skills to help pay Mozilla’s bills.
Let’s resolve this, please.
I’m not sure Max is motivated to get the add-on back on Firefox. Can’t blame the dev.
Anyway, try this add-on: Improve YouTube https://addons.mozilla.org/en-US/firefox/addon/youtube-addon/

Shame i just found this to day…
I had the extension still have it running its a great tool…
I wanted to give it a review and well its not there anymore…
Those haters who said the app does not work they did not know how to use it for sure.
But the tool is really actually kinda powerful and useful in the same time.
Damn shame they pulled it back.
I think both are tho blame here. Mozilla for their glacial review process and Maxine for not being on top of his own addon. It’s ironic that v3 was released for Chrome and Edge last year and based on comments it works fine even with YouTube’s constant changes. Yet the developer has not bothered uploading v3 for Firefox in over half a year.
Instead he was mocking around with broken v2 versions. He clearly has working v3 code. Making a Firefox addon based on that is not rocket science. Instead he decries Mozilla’s slow review process, but it’s problem he himself made worse for himself by having to constantly reupload v2 for minor fixes.
It’s been over half a year. I dont what stopped him from creating and uploading v3 in this time? Even if Mozilla took say weeks to approve of v3 – at least users would have a working addon. And since v3 requires much less fixes the slow review process would not affect him as much.
Don’t get me wrong. I still want Mozilla to fix their review process. Im not defending them. But i also think the developer lost interest in the Firefox version years ago.
Personally i used his addon for years, but it got more broken and problematic as time went on. Earlier this year i finally gave up and uninstalled it as several core features such as automatic speed (description expanding stopped working completely) worked so inconsistently that it was and exercise in frustration.
I installed Improve Youtube and im happy. It works as intended and hasn’t broken for me once. I see it’s updates have been roughly 1,5 weeks apart. Clearly that developer does not seem to have a problem with staying on top of Youtube updates.
I hope at least something good comes of this. Mozilla needs to focus on it’s core business and stop pissing of the remaining developers and users.
Well, that’s nonsense you wrote. He updates version v2 because it’s better. Just like version v2 of uBO is better than v3 (Lite). And for Chrome, he updated to v3 because v2 versions can no longer be published there.
Really pity, it’s the only browser extension I’m aware of that has a auto pop-up video window that stays up in upper window as she as one is scrolling down.
If someone knows another extension for either Firefox or Chrome having this feature then please reply.
???
I must fully agree, there are several pip extensions, but it require user to activate pip every time, another super annoying things is that the pip window is open in lower right corner, yes it’s possible to move the pip window, but it never remember the position when opening a new tab under same session, same terrible behavior for both Firefox and Chrome browsers.
Another annoying things is it dims down video quite a lot when using for instance play and pause and it takes several seconds to go back to normal, why is this all needed when every video website have such a well working GUI, it’s weird how the developers came up with this dumbed down design.
atm I only use Enhancer for YouTube for a few of its features – controlling speed with scroll wheel, setting different resolution on full screen and disabling autoplay. I hope that these features stay working for a *long* time!
For the majority of tweaks I use an extension called Untrap, though I feel like these large ‘monolithic’ extensions are easier to break, or can cause issues more easily when YouTube changes something. But for the tweaks I have selected it works well.
I used to use Enhancer a lot, it was good. However I have been using ‘Tweaks for YouTube’ a lot the past few years. It seems to have more features.
You gotta wonder if Mozilla’s review team is just stacked with moles. Funny how these “coincidences” always pop up right when the moment Chrome screws up.
And if the creator of the add-on made the unsigned extension .xpi file available, we would take care of installing it with Firefox Developer Edition.
