Firefox for Android Community Forum

I have updated to the latest Firefox version for the Android app, using Samsung Galaxy S20. When viewing YouTube in mobile view (desktop view works though) through the browser, the comment section seem to be invisible and not showing. I have tried fresh reinstalling, and toggled all the settings, but I can't seem to get it to work on Firefox. Other browsers like chrome works just fine. Is this a bug?

Long pressing the Android back button on the navigation bar no longer displays the tab's history on Firefox Android.

S22 Ultra Android 13

134.0.1 (Build #2016067655)

Several websites I've visited on my Firefox-Android browser generate a popup message that requires me to "enable java script" if I want to gain access. All FAQ I've searched so far says that Firefox enables Java by default. When I navigate to 'site settings' on the Android app settings menu there are no adjustments one can make at all. So . . . (1) Is Java enabled by default on the Firefox Android browser, and (2) Would any kind soul who knows what's wrong clue me in, regardless? Much thanks in advance!

The long-press back button no longer summons the tab's history on my Android phone or my Galaxy tab. Mozilla appears to have disabled this feature quite recently. I'm referring to the small arrow in the lower right-hand corner that you hit quickly to go back once. It was quite useful to do a long press on the arrow and have the history of the tab pop up in a list. You could then pick any page on the list and go directly back, skipping over all the other pages.

Please reinstate this useful feature?

There used to be a forward arrow option in the three button menu. Now there is not and I cannot find out where it is or how to navigate forward.

This seems like a bug because navigating forward is a core function of browsing. Anyone know where it went or how to fix this?

I just discovered a bunch of installed extensions in the list I don't recognize, including several I definitely would not be interested in.

Is this the way Firefox android works?

Firefox on Android (and Windows) keeps signing me out of any and all accounts.

I never noticed it until last month (January '25)

Example:

-> I log in to an account (and I am talking about accounts that I have saved in Firefox password manager) -> I use the website -> I check back into the browser after 2-3 days and like magic, I am logged out. -> I go to Firefox on Windows and it keeps doing the same thing as the Android app (logging me out of website(s) even if I signed into a website(s) 2-3 days ago), It was not like this ever on Windows before I installed Firefox on Android.

Some prerequisites:

1. My enhanced tracking protection level in Firefox is standard.

2. I only use one extension: Ublock Origin on Android. (and A LOT more on Firefox Windows, some of which are ViolentMonkey, Return Youtube Dislike, Search by Image among others.)

3. I do not have private browsing always on for any tabs or pages I open.

4. I do not have 'delete browsing data on quit' switched on for any setting (history, cookies, etc).

5. Firefox is my default browser.

6. I have not cleared cache or storage from Firefox.

7. I do use Firefox on more than one device. One is this mobile and another is on Windows. Both share the same Firefox account. (and I AM having issues on my laptop as well in terms of having to sign in a difference of 2-3 days.)

8. Firefox on Android and Firefox on Windows are both up to date with latest versions installed.

9. No kind of battery and/or app restrictions are imposed on Firefox on Android.

10. The 'Remove permissions if unused' option is unchecked in the Mobile Settings for Firefox Android.

Firefox on my Laptop (Windows) was facing the same issues ever since I installed Firefox on Android, it would keep logging me out of websites within a gap of 2-3 days.*

• Update: As of 20th Feb, '25 It has been 4 days since I uninstalled Firefox on Android and so far I have not faced sign-outs/log-outs on any websites in Firefox on Windows and websites that I logged into a month ago are still logged in with my account credentials.

Part 2:

Firefox on Android keeps reverting back to Factory settings and keeps logging me out of the app as well as signing me out of my Mozilla account

It started off with me only getting signed out of my accounts on mobile but now Firefox itself keeps reverting back to it's default setup AND keeps signing me out of my Mozilla Firefox account and the Android app as a whole. (my session/profile keeps getting removed from Firefox Android)

Things like:

1. Theme changes back to 'Follow Device Theme'

2. Permissions change back to default (stuff like 'Allow screenshots in private tab' whilst still being enabled, like I intended it to be- does in fact not allow me to take screenshots in private tab anymore until I flick that permission from enabled to disabled to enabled again. So it looks enabled but it is still set to function on the default perm - which is disabled for new user- only problem is I am NOT a new user and this happening because Firefox on Android keeps signing me out of the app and my Mozilla account as well as deleting my preferences.)

3. Site Settings are all reset and back to their factory default

4. Firefox Suggest and similar search settings have default permissions

5. Whenever my Firefox reverts to it's default settings like this, it has trouble syncing to my laptop (both use the same Firefox account) and syncing up the tabs from the laptop on this, or even just the data like history and passwords too.

6. Anything I might have disabled/enabled in any type of setting(s) is reverted to default. Nothing stays persistent anymore.

This Firefox reverting to factory settings thing has happened thrice already this month (February) and I feel hopeless, frustrated and lost.

Update: I tried installing Firefox on Android again on 17th Feb, '25 and when I signed in with my Mozilla Firefox account- it treated that mobile/Android device as another one than the one my Mozilla Account recognised as my mobile account (which is named 'Firefox on my realme phone') and since it recognises it as a different account, the tabs that I had opened in my original Android Mozilla profile/account are now gone as seen in the attached second screenshot- 30 tabs.)

Update: As of 20th Feb (the day I am writing this), '25 It has been 4 days since I uninstalled Firefox on Android and so far I have not faced sign-outs/log-outs on any websites in Firefox on Windows and websites that I logged into a month ago are still logged in with my account credentials.

I apologise for my english for I am not a native speaker, I will co-operate with any volunteers who can help me solve this problem. Thank you so much in advance! <3

When listening to YouTube in the background, sound is distorted and stutters frequently, which makes it pretty much unusable. Audio is okay when Firefox is in the foreground, but as soon as I lock the phone, audio stutters appear.

I found one fix on Reddit, disabling HD sound in developer options, but I was unable to try it since nobody explained how to get to these developer options, I wasn't able to find that setting myself.

It started happening since 135, was in beta as well. I opted out of beta because of it, but it came on stable release as well so now both beta and stable versions has this issue.

Has anybody encounter that or have fix?

Since I upgraded to the latest version, Firefox is sluggish and crashes on a regular basis. I have changed my privacy settings from strict to default, has not changed the problem. How can I go back to old version? I choose Firefox because of the privacy concerns, and understand that some websites won't work well, but I've never experienced consistent problems with the app crashing.

Version 133 Android pie. Unauthorized background data usage even when set to denied. System is set to deny background data usage, no exception yet firefox using data. Hate to put firefox on firewall's deny list. Is the future of firefox releases.

Firefox for Android on Pixel 8: When trying to use the Google image search in the browser or the search widget, there is no shutter button or any other camera controls—see attached screenshot. I have uninstalled/reinstalled FF multiple times and have rebooted the phone. This feature works fine in Chrome and the Google widget.

Since version 134 of Firefox Android has been out, it crashes EVERY TIME when I try ot use the "back" gesture on my Xiaomi 14(i.e. swiping from right or left side of the screen) I tried Firefox 134, Iceraven 2.27 (also based on the same Gecko) - they act the same. In the same time I also have Waterfox, based in the previous version of Firefox 133, and it responds properly. I guess it is related to the latest version only. Here's the crash log:

Hello

I have always been using mozilla firefox as my day to day browser. However, After recent upgrade of my device to Pixel 9 pro XL I am considering switching to Chrome as I experience inconsistent scrolling and stuttering. It appears as whole scrolling down the page the refresh rate drops to zero for fraction of a second. I do not experience this issue on Chrome. I tried using Firefox without extensions too, but it does not help. Changed several settings in about:config, and it did not help to improve. I am on a clean install now and ready to try any proposed solutions which might help. Thanks in advance,

Martin

Hi, I think there is a connectivity or audio code problem because when I'm using YouTube on Firefox browser there is a crackling sound on all videos (I am using smartphone and Bluetooth headphones). On Chrome, it is not present. Please fix it.
