Firefox til Android supportforum

I have noticed that for the past several months Firefox for Android begins draining my battery after being installed for around 2 weeks. I'm using a Google Pixel 7 (128GB) running Android 14 (AP1A.240405.002) in the UK.

At first, I thought this was being caused by an add-on, so I reinstalled without add-ons and slowly started enabling them day by day until I caught the culprit (which if I recall correctly was Dark Reader). However, even after I disabled the Dark Reader add-on the problem persisted, and no matter how many times I uninstalled and reinstalled the app, the background battery drain issues would eventually come back after ~2 weeks of being installed.

At present I have only three add-ons enabled in the browser: ClearURLs, Decentraleyes, and uBlock Origin. I have used these add-ons in the browser for years without any issues.

It's now got the point where I am so fed up with this issue and the need to constantly reinstall that I will be using a different browser for the time being until this is fixed. I really want to use Firefox as I use it on all my other devices, but this is too much of an issue for me to ignore.

I've included screenshots of my phone's battery consumption whilst I'm asleep, and whilst I'm watching Youtube on my TV over lunch. Both of these are times I'm not using Firefox.

Any help on this issue would be greatly appreciated.

Hi Guys!

Can high resources eatin' (maybe graphics, IDK) Ads, for Me in the Webside embedded and (sometimes) with 'movie' like movement decorated, automatically get blocked?

My phone runs slow, 'even' with just 1 Tab open and only Firefox Mobile App on the phone active.

Sorry, I can't see the field I type in currently, maybe I writ a bad layout right now, but content matters XD.

1. Sometimes I use the browser while the system is in dark mode.
2. Then I switch system to light mode. FF recognizes it and switches to light mode accordingly.
3. Then I use it in light mode for a little more.
4. Then some time passes (maybe a few hours), I don't use FF during that time.
5. Then, I tap on FF icon, the browser starts, but immediately switches back to dark mode, while the system is still in light mode.
6. I have to close FF by swiping on it in task switcher, and then tap on the app again.
7. FF now uses light/dark theme according to system.

I am using Fennec: 124.1.0 (Build #1241020), 516df33ca9+ GV: 124.0.1-20240326023132 AS: 124.0

"Hi there! I've been experiencing some difficulties with the Mozilla Firefox mobile browser on my Android device. Whenever I try to open certain websites, the browser crashes unexpectedly. I've tried clearing the cache and reinstalling the app, but the issue persists. Could you please provide some guidance on how to troubleshoot this issue or any possible fixes? Thanks in advance for your help!"

I use corporation's websites to find its workers phone numbers. Websites for all regions around the country have the same layout but sometimes frames with names, adress and phone numbers are individualy designed.

I use mobile browser on Galaxy S series smartphones. When I mark phone number it is not recognized by any dialer. When I try the same on other browser i.ex. Brave it recognize it without any problems. No matter how web frame is designed.

I guess this is an issue for Mozilla developers to check out. Personally I dont see any custom settings to change it.

When displaying an iframe video in a popup, clicking the close button and other click events do not work. This issue only occurs in the Firefox browser on Android, while it functions correctly in the Firefox browser on iOS.

Is this a default behavior.

Using Firefox mobile for android and GBoard.

I've selected Firefox as my auto fill service.

A few official apps (at least one banking app, for example) that I've downloaded from the play store that report the following after I unlock and select the correct password:

"Firefox could not verify the authenticity of the application. Do you want to proceed with autofilling the selected credentials."

I can't seem to find any other report of this error so I'm curious what's going on.

I said it all in the in the opening statement... What else am I meant to say?????????? It worked fine 2 weeks ago..? But now forget it!!!!!!! What has changed....you must know ... So don't ask me just fix it!!!!!!

I thought half my apps were gone randomly, then I realized they are all the ones that were web pages Saved to Home Screen, by Firefox! I'm very upset because there's no way I can remember all of them, how can I restore?? Android, no desktop fixes please!

Logged into Mozilla, Sync now does nothing, "Last synced: never" Also crashes frequently all since last update.

When i use mozilla in android 13 tablet, and i click on the 3-dot menu while the address bar is set to appear in bottom of screen, i cannot see the full 3-dot menu neither can i scroll to the end of it -only half od it appears. When the address bar is set at the top of the screen,the problem does not exist in landscape view. Please fix it

I just did a Google image search on my pixel 8 and saw that all the image results were forced to "fit width" so I can only really see 1 result at a time. I have the "Google Search Fixer" installed and dialsabling it returns the image search view to gallery. But when I enable to addon it goes back to that "ft to wish" view.

I've looked through the options and tried searching for similar problems/solutions and found nothing. How do I return my Google image search view to gallery? It's really obnoxious and frustration to only be able to see 1 image at a time when searching.

When playing a video on YouTube the video is choppy and drops around 2/3 of the frames. This happens on every video that I click on.

I have found that if I double tap to jump back 10 seconds in the video it will no longer drop frames and play smoothly, but if I change the playback resolution it returns to being choppy until jumping in the video again.

I am currently running the latest stable download from the play store, and my phone is a OnePlus 8t.

Dear Firefox team,

Since the two or three latest Updates of your browsers, a strange bug occours everytime watching a video. When I pause it and let it play again, the video goes under quite some lagging/stuttering. The audio is fine, but the video is not on screen is not. I have to go back on the video bar, so it runs smoothly again.

And before it comes, I already tried the usal methods, such as clearing the cache, clearing browser history, cookies, used privat tab, deibstalled adblocker etc. Nothing worked, and it happens even with different versions, such Firefox normal, nigtly, waterfox etc. And with every video player, not just a specific one. And I teued it on two different smartphones. Is there any solution or planning to fix this?

Lately, Firefox for Android has started "forgetting" active tabs. I have changed absolutely nothing in the settings. Most of the Active Tabs I've had for years are gone. Now I only have about 5 left & they get corrupted every couple of days. For example, the 3rd one in the attached Screenshot: I'm playing "catch-up" on old Guardian crosswords, currently on 15,179. At irregular intervals, say every couple of days, it gets replaced with an older one, 15,166 for example. I suspect it must have been changed in the Version released on March 19, 2024 (124.0)

Triggered usually by any Website with a (google) map.

   Chrome on Android 13 on the Oukitel RT5 displays these Websites properly.

'Split Screen' functionality & gestures useless. The appear they might work until finger contact with the touchscreen is discontinued, then every attempt rebounds to half the screen still black.

  The only 'way out' of 'split' screen is to exit FF.

There appears no way to 'disable' Android's split-screen functionality

YouTube videos cannot be played in 4K resolution on Firefox; the maximum supported resolution is 1080p. However, when using Chrome browser, 4K playback is supported.
