"How can I troubleshoot and resolve common issues with my Mozilla Firefox browser using the resources available on the Mozilla Support website?"

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!!!!!!

Firefox Update 124.2.0 (Build #2016012559), 7a0e399c7b+ GV: 124.0.2-20240401114208 AS: 124.0

Fire HD 10 (11 generation) Build 0029294005124 FireOS 7.3.2.9

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

I recently noticed that the reader mode is gone from every website I visit on my android device. I've confirmed that the same websites have the option available on a desktop browser. This might be related to, but isn't entirely the same as, another issue I've read about here where the reader mode throws an error. My issue is different in that the reader mode simply isn't available. I don't get any error messages because there is no icon to click. Version 124.2

Anyone know if this is the same or a different issue? I almost exclusively read websites via reader mode so this is a significant impact to the way I browse and read things on my mobile device. Any help would be appreciated!

This screen displays brackets in the corners defining the corners of a square in the middle of the screen. You cannot pinch it to make it larger or smaller or smaller. If you scroll up on the windows it closes Mozilla. The only way to get rid of it to use the browser normally is to reboot my Samsung phone.

Video of the issue

If i open a link to redirect to an app, let’s say wikipedia, it will redirect fine. When i switch back to Firefox, the mobile version of the link i clicked on will be loaded instead of just displaying search engine search results where i clicked the wikipedia link. (Admin note: edited to fix formatting issue)

Another thing that happens is if i click on the link, still being wikipedia, get redirected to the app, then close out firefox, the next time i open firefox, it will redirect me back to the wikipedia app.

This issue I have been having is not just related to Wikipedia, this is for any other link that may open a related app I have installed on my phone.

I have read the thread for this similar problems, tried all the suggestions but I'm Still experiencing videos not staying full-screen. Is there any other solution to it? This has started since yesterday but everything was fine before then.

"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 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!

I use a samsung galaxy A12, and I have issue with the download functionality. Whenever I'm downloading and I pause or the Internet becomes bad, when I resume the download or "try again", it completes the download but the file becomes corrupted and won't open in my phones storage. And I notice that the size of the file is always less than the actual size downloaded, which indicates that it stopped downloading into the local storage at the point it paused or network became bad.

It'll download completely, but the file downloaded into the phone becomes corrupted and useless. It's annoying that a browser has such a problem in 2023.

Please, fix up ASAP.

I'm trying to add a new Google Gmail account I just recently created to my iOS 17 iPhone 13Pro Gmail app and it's telling me I need to use a browser that has JavaScript enabled. I'm using Firefox as my default browser. How do I enable JavaScript so that Google will let me add my new email account?

Thanks for your help! Seems many have this problem and no answered in the support data base.

Hello,

I am getting a frequent freeze in the Android app and then shortly after a crash. Info: - happens on FF, FF Beta, and FF Nightly,and reinstall/phone reset didn't fix. - Samsung Galaxy SM-G965U running Android 10. - every error starts with java.lang.OutofMemoryError. - it never happens just on startup, just on auto fill, or some of the similar crash reports I've seen around here. - it does appear to be site-specific, but sometimes the site works and sometimes it does not: if I close the last tab after a crash, it will usually work for awhile. - Sync and disabling Add-ons doesnt fix it, although perhaps its worse with uBlock Origin enabled (not conclusively)

Thanks for any suggestions.

Hi,

I have been watching YouTube videos on firefox android and have been clicking ful screen and landscape has been fine. Then over night a few days ago, it stopped. When I turn the phone to landscape, the video sound is playing but the video is blank, with no picture. It is fine in normal portrait just not when I click full screen when it was working.

I've cleared the cache and history, I've even unistalled Firefox and reinstalled it twice, once from the play store and once as the apk but to no avail. I have also disabled adons, tried the picture to picture, and autoplay but nothing works.

Any help to rectify and return my viewing would be appreciated.

Every time a youtube video is placed on landscape mode on the firefox app of my android phone it becomes a single blurred image with the audio playing as normal.

Youtube seems to work fine on other browsers and I have tried all basic fixes, like deleting cache/data/reinstalling app etc. Appreciate any help.

Edit. Okay I managed to fix the issue so I'm adding the solution here in case anyone runs into this problem. Apparantly youtube playback decided to enable "ambient mode", a feature I didn't even know existed and seems to not play well with a phones resolution.

Just click the settings gear while the video is playing in landscape (mine is on the top right) and disable the "Ambient mode" feature.

Hope this helps.

Hello! A little embarrassing but I used 123movies to watch a movie, and afterwards I keep getting a notification from my anti-virus software that says that 123movies wants to gain access or is active.

I want to block the website i have visited to hopefully solve the problem.

how do I do that through the iOS app on my iphone?

thanks!

‘Pay with PayPal’ functionality on websites is broken for me and has been across updates of both Firefox and iPadOS for as long as I can remember at this point. I’m using an iPadPro running iOS 16.7.2 with Firefox for iOS version 120.4 (36613). When I’m checking out at e-commerce sites (e.g., J Crew), and I click on the PayPal button when selecting a form of payment, a new tab opens, but it’s literally blank — nothing even tries to connect or load. This happens across e-commerce sites. It doesn’t happen with Firefox on my PC/Windows laptop or on my iPad with other browsers (Chrome, Safari). I have tried everything that I can uninstall/reinstall, deactivate, or toggle, and nothing seems to fix this. I have cross-site tracking disabled in iOS. Some people have suggested that websites are not fully supporting Firefox any longer or that there is a problem with Firefox and Apple’s proprietary rendering engine. I’m really at the end of my wits about this. After having used Firefox faithfully since Netscape disappeared, I’m honestly on the verge of giving up. Please help.
