Firefox for Android Community Forum

After the last update, your browser is lagging on youtube web, every time I press a button, it takes 5 seconds for the button to respond. Will Firefox bring fix solution for this ?

I have been using uBlock Origin for years to block ads in youtube. Recently I started getting ads again and when I checked I found uBlock was disable snd couldn't be enabled. I dl the latest version but it gives me an error message when I try to load it. Please help.

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?

136.0.2 (Build #2016079799)

Latest version (version above) on Android appears to have issues on startup of displaying shortcuts on the homepage. It doesn't initially display them, but if I select the private browsing symbol, then select it again to return to normal browsing, the shortcuts reappear. Then when I start Firefox later, having closed it down for a while, the same issue occurs.

Also, from not showing the homepage icons, clicking the '0' and clicking the '+' to add a new tab displays the icons.

Firefox used to start up and display the shortcuts without having to go through the above process.

I've tried various settings for the homepage but none resolve this.

Anyone having the same issue?

Screenshots attached.

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!

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

134.0.1 (Build #2016067655)

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?

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?

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?

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?

Hello, i am having an issue with firefox mobile for android not loading certain websites. This seems to happen randomly and i cannot figure out why. When i click on a website url from the search page i sometimes get the error message, "Server Connection Failed", and i cannot get the page to load at all. I have tried to clear my cookies, clear my cache, uninstall and reinstall firefox as well as update it but it still keeps happening. This has been going on for years to the point where i am forced to use other browsers to get certain pages to work and load properly. I dont want to leave firefox because i really need the dark reader extension app because i have photo sensitivity due to epilepsy.

Can anyone help me figure this problem out or offer me an alternative browser where i can turn every page that i search to dark mode like the extension dark reader?

Thank you!

Stop keyboard and QR scan from appearing when app opened. If I want keyboard then I will tap search. I have pinned sites and bookmarks I use first and usually don't use search. Using search less with all the tracking and always wrong AI assumptions. Keyboard doesn't disappear when search is tapped. Doesn't disappear when screen is tapped. Obscures results. Been a problem for years.
