Firefox for Android Community Forum

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?

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.

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.

This has happened to me for days now. Firefox keeps hiding a portion of the page, and I have to zoom to see the parts that are hidden. Can someone help me with this error? (tor). Disabled all extensions, cleared cache and data as well.

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

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.

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

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.

After I log in to Linked in I can not use profile or network pages, as it looks like some kind of semitransparent overlay is displayed above them, preventing me from interaction with the page. In the same time home feed is working fine. I tried disabling all extensions but no luck.

I'm everyone working on Firefox is absolutely sick and tired of hearing from us Android users bellyaching, usually about incredibly ubiquitous, very basic features, which somehow only affect our OS, so let me apologize before I begin, and yes I do know it's a bug, and read a rumor Firefox 57 may fix it, to keep your reply as minimal as necessary.

I recently migrated back to you, and while it hasn't been any complex issues, I spent an figuring out I couldn't simply open my browser to a specific URL, though yes I did apply the quasi-work around option of making it a permanent page/icon, which I can click, though this took another investigation in itself, because for some reason Google News(web based url) doesn't doesn't even list as a website in the hamburger menu, which changes it to an app. Yeah, it is indeed an app, but I'm using the URL so this just seems like it was built to confuse, which thankfully a post on Reddit made crystal clear, along with plenty of company of other confused people.

Now my next issue I now know I can't even fix, but simply would appreciate an idea of when/if the bug will be stomped. I, of course, have a couple of fillable pdf files I need to fill in and email, so during my breaks yesterday I finally found(tons of answers out there obviously between old builds/OS) out this was a bug, and Android users simply cannot use web based pdf editors till it's repaired (I'm an old school programmer, detest downloading any app I'm not power using, especially if there's a web based version, even Google News that I read constantly, I stick w/website, because as you know we already have more apps than our hardware's performance can handle. Found a github post, stating this might be fixed in Version 57? I looked at the About Firefox, and saw a 119 number, but it wasn't clear if that was build, or what number there was. I just downloaded Firefox, so do you have any idea when/if any of these very basic features are going to be fixed?

From my reading, it sounds as if this new Android build is still very much in it's infancy, and understand it takes time and updates to get things high and tight, and I wouldn't even be bothering you had I found anything here or elsewhere that wasn't utterly vague. So perhaps first, when is the next build due, and second, is there any specific info as to what we can expect to see fixed and third will there be a homepage button, that we can put a specific url in along with regaining the ability to view/edit pdf files that are web based? I, obviously am just going to have to use my old ad ridden browser to accomplish this, but I'd sure like to stay default with your browser after spending all this time making it just that, and forbthe fact that otherwise, Firefox Android has accomplished everything else I was hoping to nip in the butt,along with finally getting back my ability to highly customize my browser. Sorry again if there's an answer here to all of this, I really did make an effort to find something too, and thank you for your time.

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

Hello All, For some unknown reason, the browsers available on Play Store for Nvidia Shield are crap - so far I've not found any that allow me to easily sync bookmarks etc between Shield/PC/Mobile.

I therefore tested and found Opera and Vivaldi sideloaded to my Nvidia Shield TV Pro both worked perfectly.

I wanted to use test Firefox as I was about to use this as my main preferred PC/mobile browser, but first I wanted to check it all worked OK.

I was able to sideload and set up Firefox, but as soon as I open a webpage the Controller stopped working.

How can this be fixed please?

Please don't suggest a browser that's intended for AndroidTV on the Shield Play Store - they are all crap due to the reasons I mentioned, the controller with Right Joysick acting as mouse pounter works perfectly on Opera and Vivaldi, so I don't understand why this it doesn't work on Firefox.

I hope this can be fixed/resolved as I would like to use Firefox as an alternative.

Thanks and regards!

Andrew Henshaw.

Tabs on android app "unload" themselves whenever I minimize the browser I'm 100% sure I've toggled an option to kill apps when they're minized in phone settings, and thus issue only happens with the Firefox browser and nothing else. I have the latest version.
