Firefox for Android Support Forum

I have been seeing these annoying colorful dots popping up on websites that ruin the otherwise excellent browsing experience. They sort of move around as I scroll. They aren't limited to specific websites and show up randomly.

When they strike, certain site elements disappear too - like the social sharing badges in the screenshots I've attached.

Thought it was a temporary problem that'd be fixed with an update but it's stuck around for months now.

Anyone else facing this problem?

Firefox is working in background and draining the battery. That what I see in battery usage information. I have tried to limit and stopped Firefox but it is still on the top of battery usage.

Hello everyone.

I'm noticing an abnormal battery usage in my Samsung Galaxy S24 Ultra. Ive used other Chromium based browsers without issues. Sadly I'll have to stop using it.

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

Websites are mostly reporting that my browser Firefox Android latest needs advanced or enhanced Javascript support and about:config no longer works.

All sites working in Microsoft Edge for Android.

After I want to multitask on my phone and switch between the browser and other app. The page becomes blank and refresh button doesn't work.

I need to open a new card to continue using the website loosing all temporary changes made to it.

Redmi note 11 pro 5g with 6gb of ram

Issue was present for at least 6 months.

Sometimes, when I type a search query or a page address and hit enter, nothing happens, the keyboard is closed and nothing more happens - a blank page - no loading or anything (the same applies when you try to type a page URL).

I use the latest Firefox (124) on Sony Xperia 5IV.

I could attach a video but unfortunately only images are supported.

Dear team, 1) thanks for your work! 2) I can observe a quite important problem which could make me uninstall the app. Mozilla is now draining much power, even while not using it (e.g. at night where I can monitor the problem). I can observe that since I switched to a pixel 8 phone. (Which has itself a poor living battery). The phone can hardly survive a day and a night without being charged. And when charged on everything. It can loose up to 30% battery until the morning. Another phone could be 5%. What really strange is android show me that during that period of time Mozilla was responsible for 90% of this leakage. I had sync enabled.(Tabs, history and bookmarks) I removed it, but the leaked percentage of Mozilla at night stays around 70%.

Steps: - create an iframe without src - create click event listener on any other element - set iframe src to on click to some url that supports "go to application" e.g. YouTube embed url

Expected: Iframe shows youtube video on element click

Actual: Firefox asks to open a new tab or open an app, and never shows this in iframe

Fix for developers: Recreate the iframe with the src

It only works on ff android, we spent literally hours to catch this bug

When a private tab is opened, it lets me know in the silent notifications on my phone with the "swipe or tap to close" the tab/s. However, once I close the private tab that notification remains. When I click or swipe the notification it goes for a second and comes back despite not having a private tab open. Even with normal tabs open it does the same thing. Force stopping the app gets rid of it but the second a private tab is opened it returns.

I understand I can just turn off that notification but it's useful to have. Was just wondering if there is a fix or setting anyone knows of or how I can report this to Mozilla?

Thank you

Hello,

I'm facing a severe battery drain issue that occurs with all of the current Firefox versions for Android (Stable, Beta, Nightly). I have noticed that the problem mainly arises when I have played any type of video through the browser, such as a YouTube video or any auto-playing html video through a website. And I don't mean that the battery drain occurs WHILE I have the browser open, I mean in the background, after I have exited Firefox. I have also installed GSAM battery monitor with the necessary ADB battery stats permission given, and it seems that the "Video On" wakelock is always on with Firefox. It's like that the thread that plays the video has not stopped, even if I have force closed Firefox, and killed the video tab. For example, I'm attaching two screenshots from the battery monitor, where I have previously opened Firefox and played a video for like 15 seconds (see the "Audion On"), then immediately closed all the tabs and force closed the application. As you can see, the "Video On" has not stopped, like the "Audio On" wakelock, and continues to count (35 minutes). This may go on forever, such as if I leave the phone at night, I'll wake up the next day with Firefox video wakelock displaying something like 15 hours of playback (something that of course, is not true). The only way to stop the drain, is to restart the phone and not open Firefox.

Though, the issue may not even be related with video playback. I have read in the forums (like here: https://support.mozilla.org/en-US/questions/1432706) that other people are facing this issue as well, and worked around it by not using Firefox as the default browser. I have not tried it but, even if it works, this is not at all convenient. Other posts on reddit that verify the same issue I am having: https://www.reddit.com/r/pixel_phones/comments/18xh7w3/why_is_firefox_using_all_this_battery_i_havent/ https://www.reddit.com/r/zenfone/comments/18zlow0/since_android_14_video_seems_to_be_the_top/ https://www.reddit.com/r/firefox/comments/174d13d/firefox_excessive_battery_usage_on_android/

I do not wish to switch to chromium based browsers. Please take a look at the issue and let me know. Thanks a lot.

On my S24 when I use Firefox the screen starts flickering and it's impossible to navigate. Only fix is to restart the phone. Online there are lot of users of the S24 series that complaints about this issue. Can you please provide a fix? Or I will have to find an alternative for Firefox

Recently I noticed that occasoinally if I try to load a new page on a new tab it will not render. Sometimes it helps if I close it from the recent apps and reload Firefox. Last ti.e it didn't helped. This time what was interesting I tried to switch to a not yet loaded page, it was also black. Than I switched to a page with a preloaded preview it flickered for a bit and than the issue resolved itself. The affected device is a newly installed s24 with exynos s2400 so I'm not sure if it's a driver issue or is it a firefox bug. I didn't notice any similar with other apps.

Hello Mozilla team.

I need your help with the following: I recently upgraded my device and I got Samsung S24+. Unfortunately Mozilla is not working properly. Whenever I open a new tab or open a link via my email account it is flashing constantly without being able to browse as usual.

Any help? (I have already unistalled / reinstalled the app.

Look forward to hearing from you

Kind regards

Firefox has been a great browser on my new S22 however I have noticed recently that it has been dropping my battery percentage extremely fast, and I notice its lower almost every minute I check. This is confirmed in the battery settings menu where it shows an abnormally high amount of usage, when I mainly use Firefox for general browsing and close background tabs.

Hi,

I am using Firefox on Android and every few minutes it will just refuse to load the page. This doesn't happen in Firefox on my laptop so I don't believe it is an Internet speed issue. Often it will just not load and timeout. I usually quit Firefox and clear the cache and that seems to help temporarily but a few minutes later it's doing it again. It's becoming unusable at this point and I have read posts from other people with similar issues. Can we get this fixed in general please? I couldn't find a way to contact Mozilla about this.

Does anyone have any tips or settings I can change to eliminate or reduce this problem?

I'm on Android 13 and Firefox 122.0

Let me know if need any other info. Thanks.

Keep getting the message on new Tab page..."500 Internal Error". Tried a search of it, found correction suggestions...did a soft & hard reboot=nothing. Tried finding the Firefox Cache, that said to delete, but can't find that file in the Settings tab in Firefox. So can't do any searches in Firefox for 2 days now. Can you help to resolve this? Or, do I have to delete Firfox & go to another browser?

About half a year ago, there was a problem with parts of webpages being blocked out by rectangles in background colour on some Android devices. As I understand it, that was a problem with hardware optimization on Adreno 308 GPUs, as my phone has. The problem was fixed in 116.

Now, in 121 (and possibly earlier), the problem is back on my phone with this GPU.

E. g. on https://tvtropes.org/pmwiki/pmwiki.php/Main/ForgottenTrope, there is a white block in the second paragraph, hiding a part starting with the second half of the second line and two lines more. The text becomes visible line by line when I zoom in.

I found an entry in bugzilla, https://bugzilla.mozilla.org/show_bug.cgi?id=1843749, which seems to pertain to the problem. It was closed with the fix in 116. I guess it needs to be reopened, or a new one referencing this one?

What can I do to set the wheels in motion so the problem will be solved once again?
