When attempting to enter full screen mode on Firefox for Android, and to get into landscape mode, the browser appears to crash, keeps audio playing, and "entering full screen mode" dialogue pops up. Have to open Firefox again, and can only be viewed in landscape mode while session is continued. To return to non-landscape mode, the app needs to be force stopped, otherwise you only get to see the left one third side of any web page you navigate to. Seems to have started with most recent update. Is there any way to fix?

Just updated to latest version of Firefox for Android (ver 113). When I try to watch a YouTube video in full screen, the app suddenly closes, as if I pressed the home button (note: I say "close" rather than "crash" because when I reopen it, all the pages are still loaded). This doesn't happen every time, but it is annoying. Is there any way to fix this?

Firefox crashed on me. And deleted all the tabs that’s I had up on Firefox. It didsk me if I wanted to restore my tabs and I said yes, but none of them got restored. And I can’t seem to find any recent tabs or anything!

Hello, I have had issues with multiple crashes with Firefox for I Os, now when I try to access my xfinity email, I get the to and from but not the body of the email. I updated Firefox and rebooted my iPhone but still the same results.

When reading the site https://hellasjournal.com after a while Firefox freezes and crashes. It's not a site problem because with Chrome works fine.

Hello everyone

I'm at a loss. FF for iOS (iPhone 7) keeps crashing every few days (no other apps have similar problems). It then asks to restore tabs from the last session, which mostly works, but every few weeks, all tabs are lost (about 20..50 total). In history menu, open tabs from last session is greyed out. When the tabs are are lost, they're also instantly purged from FF sync. >:(

I'd love to use FF on iPhone, since I'm using FF sync extensively and successfully on multiple PCs. But on iPhone, FF only causes me pain and suffering (i.e. the need to comb through months of history in the hopes of catching all lost tabs). Is there anything I can do that FF on this platform gets more reliable?

It seems, the more connected we get, the more data we lose. :(

Best regards

Björn

Once a while Firefox would freeze up and when that happens it would without fail reboots the phone if the phone goes to sleep and if I don't force close the app quickly. It might've done so anyway without putting it to sleep but I haven't tested leaving the screen on long enough. I noticed that if I was quick enough and force stop the app the phone doesn't reboot, but that window is really short. Maybe 2 seconds or so. Suffice to say force stopping didn't always work since the window is so short. When Firefox freezes other apps and phone functions work normally. It's been ongoing for a while through multiple updates. I see some people have already reported this same issue here. Can Mozilla fix this please? I have uBlock origin addon installed thanks. Also this never happened with my Pixel 3 phone which I was using up until a few months back so maybe it's pixel 6a specific. Alot of people have this same issue with pxiel6a from googling. It can freeze on any site I visit but one example is reddit.

1. Whenever you login a site, Firefox does not remember the cookies from the login. So when you close the app and open it later, so you need to login again.

1. Firefox crashes a lot since iOS 16 and now too on 16.1, and now also since the release iPadOS 16.1. This makes the app difficult to use and really bad.

Both are very frustrating and important issue, please fix it!

My phone is on Android 13 with the latest Firefox update. Under "Crashes" in Settings, there isn't much.

Firefox has been crashing my phone for a while now. It finally was able to generate a crash log. Can someone take a look at the log and see what might be causing it? Thanks.

Old thread talking about the crash if anyone's interested.

Woke up today and ipad crashes each time i try to go to a webpage in Firefox. Worked fine last night. ios14.1, can’t upgrade this ipad now. Have deleted and re-installed Firefox multiple times, rebooted ipad, can’t even access Troubleshoot mode bc it immediately crashes and closes Firefox. Please help.

Ever since the new update my Firefox has deleted all my tabs and won’t let me open any urls. I’ve already uninstalled and reinstalled the app to no changes. The only solution I’ve seen that could work would be sending my log report, yet haven’t found anywhere to post said log. Overall I’m lost at where to solve my problem with my app crashing. For context I’m using an iPhone that’s currently running iOS 14.

I am a long time (decades) user of Firefox. I run Firefox on Macbook, Android, iPad, and Windows 10. One of the features I use a lot, is the sending of tabs from one device to another. Mostly with the iPad being the target. Recently, Firefox crashed on the iPad. Not a problem, I thought. Firefox has crashed before and machines running Firefox have crashed before. Firefox has always nicely restored tabs that were open at the time of the crash. Not so after this crash on the iPad. Selecting the button to restore tabs did not restore anything. I quickly opened the tabs that were synchronised from the iPad on my Macbook. Firefox on the iPad had lost the way altogether. There were 3 entries in the synchronisation database for it now, two with identical name. Sending tabs to the ipad could only be done to the wrong name. Renaming the machine on the iPad did not result in corrections, so I uninstalled and reinstalled Firefox on the iPad. This did not correct the issues, so I deleted the iPad Firefox devices (all for the same device) from the Macbook. That worked. After that I set up the proper name for the device on the iPad, and sync and sending tabs worked again. The next problem was that web pages that worked before did not open in Firefox on the iPad any more. Some cookie settings pages worked alright. The cookie settings page for my newspaper did not work any more. No way at all to get to those settings. The pages for my newspaper also did not load to the end any more, making Firefox on the iPad quite useless for me. I have tried several things, including uninstalling and installing again, deleting all web content from within Firefox, restarting the iPad, … Nothing solves these problems. What I noted during all these actions in Firefox on the iPad is that most of the time the Settings -> Data Management -> Web Site Data acttion kept showing a little thingy going round and round and round and round. I have only seen web site data there once. Anyway, since it looks as if Firefox does not work any more on my iPad and is not restorable, it seems, I am now switching to Chrome. I find this very disappointing, as I really like (a working) Firefox as my browser. Nice features, good privacy, works everywhere (until recently). Not withstanding that, I do need a good, functional browser. So, for the moment I am switching to the Google Chrome browser. Because I use the sending of tabs between device very frequently, I am going to switch on all my devices. I really hope to hear in the near future that the iPad issues for Firefox are fixed. Good chance that I will then switch back to Firefox.

I opened a large PDF on Firefox (among other tabs open) while checking insurance coverage. After scrolling through the PDF a bit and switching tabs, when I went back to the PDF tab, Firefox crashed. Now it opens to a white screen every time I try to open Firefox and crashes shortly afterward. I was hoping I could close tabs, or clear history, but cannot access anything. I’ve cleared all active apps and tried restarting the iPad a few times. I also tried updating the FF app. Is there any other way to get FF running again, or at leave, recover my bookmarks before I uninstall/reinstall?

Hi everyone,

yesterday I updated the Firefox app on my iPhone and since then it started to close on its own after a few seconds since I start to use it.

I am using an iPhone 13 and the Firefox version installed is 110.2. The behavior is the same as if I would close the app with a gesture (by swiping up the little bar at the bottom of the screen when the app is open). In fact the app is still running in the background, but won't stay open to use it.

Thanks for the support!
