On youtube mobile site or a reddit video, when I click the bottom right button to fullscreen the video, a message pops up that says 'entering fullscreen mode' (with a firefox logo on the left of the message) and then firefox closes and I'm at my android home page

This seems to happen when I watch videos in a new instance. If I reopen firefox to the video and then try fullscreen again, it goes full screen no problem. So basically it's annoying and happens when I try to watch any video full screen for the first time.

Is this a known bug? Wasn't an issue on my old phone (I just got the galaxy s23).

Firefox is fully updated from playstore. Only addons installed is ublock origin and Privacy Badger

Thank you for any assistance

Not exactly sure what update started this but it worked fine before. I use Firefox on s23 ultra and tab S8 ultra. Both are signed into and I've tried to reinstall the app but still doesn't fix the problem. If I go on YouTube or a website that has video, if I click on full screen the app closes down but keeps playing the video. If I open the app and hit full screen again it then works and fills the screen with the video. If I could go back to a month ago maybe since this is pretty new bug. I do have add-ons but even with a clean install and no add-ons it still does the same thing. Was referred here from the play store.

I left a critical review on the Play Store recently at the time of writing this regarding how, for years, the Firefox Android App would crash whenever I try to check the 'Downloads' page. This happened on at least 3 different devices over the years, and still does to this day. Because of this issue, Firefox no longer notifies me the time takes for a download completion in my notifications; only that it's completed once it does.

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?

My Firefox on my iPad alsways crashes when I try to select a synched tabs from another Firefox on a different device. The tabs from the other devices show up and the sync is always up to date, but the windows does not react on any interaction, instead the Browser crashes after about 1 minute of inresponsiveness and returns to the home screen of my iPad. I already discenneted and reconnected the Firefox account used for sync on this browser, it did not help. I use the same Firefox version on my iPhone and that does not have this issues, selecting tabs from other devices works as intended.

Firefox version: 114.3 (31916) iPad OS: 16.5.1 (did not work in iPadOS 16.5. either)

I've had this problem of on my iPhone 14 Mac Firefox (now v113.2 where )tabs are taking long to delete and they freeze once I try to. After waiting awhile, anywhere up to 30 seconds or more, they either finally delete, but still slow or the app crashes and that seems to make the deletions fast, like they originally used to be. I've seen that other people seem to have this problem and I just wondered if a solution for this has finally been found?

Thanks in advance to anyone who knows how to fix this...

Hi,

We use about ten Android tablets running Firefox in our shop for our employees to enter on a webpage daily some informations. Tablets are programmed to keep display active 24h/7d, firefox is pinned so the app stay opened and users don't go to other app. The extension LeechBlock NG prevent users from accessing other webistes. Everything work well except on mondays morning.

Without fault first person to try to connect on the website will see the app crash to the desktop. Since the app is pinned user will have to wait for a supervisor to come in and unpin the crashed (and invisible) app, re-launch it and pin it. Then it will work all week without issue as long as the tablet is used at least once a day. We recently added a new tablet which is used less than others and that one does crash during the week but never twice in same day. Here's the crash report that we have (I checked multiples tablets and they all share the same crash code):

Wondering if someone can help me decypher this to fix/prevent it. Is it the extension or browser itself that cause the crash if the page hasn't changed long enough? Thanks for suggestions (I will not consider "have you tried without the extension" as a valid suggestion)

I had about 500 tabs on FF on my iphone open. The browser crashed and now all of those seem to be gone. "Recently Closed" is empty. Starting the browser just opens an empty page. I had sync turned one but oh magic the synced tabs pretty much immediately diappeared from the other devices as well. Any ideas how I might be able to recover those tabs? Could they still be saved somewhere on the iphone or in the cloud?

firefox for iOS 113.2 iOS 16.5 iPhone 8+

okay, so: this has only been an issue since i updated to iOS 16.5. i can open firefox for iOS without issue, and i think if i just tapped into the search bar that might be fine? (unclear.) but what i know is that as soon as i try to type in the search bar, the app crashes! how can i fix this?

Hello,

I've told to report technical issues on this website.

I've noticed an issue with Firefox iOS where, if Firefox silently crashes and I open a new tab by doing a long press on the iOS home screen, then selecting New Tab, Firefox only opens that new tab and does not restore the previous session and all previously loaded tabs are gone.

That has happened to me multiple times now and I've had to then try and figure out which tabs I had open by going through the browser history, which is pretty annoying.

To prevent that, I'm pretty much not using the long press > new tab functionality at all anymore and instead I open the app first, then open a new tab. Sometimes, I'll open the app, and if the app crashes, THEN I'm asked if I want to restore the session. Then I have to make sure to not accidentally press NO cause it seems there's no way to get that session back afterwards.

I would suggest a few ideas to prevent this issue: - please offer a setting to auto-restore previous sessions after a crash, instead of asking - alternatively, if pressing NO, or opening a new tab from the homescreen with a long press, offer a way to restore a previous session somewhere on the new tab page

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

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.

Here's a video: https://imgur.com/a/7etdWuL

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.
