Dear Mozilla support,

For a while I have the problem that when I want to watch a video fullscreen on a website e.g. youtube, inline video etc. Firefox stops and completely closes. This is only the first time when I play the video. When I re-open the browser I can continue watching the video fullscreen without any problem. I don't receive any error messages.

Attached the specs of my phone and Firefox browser.

Kind regards, Rick

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?

Hi,

Since I've installed the latest Samsung OneUI6/Android 14, Firefox keeps crashing randomly. There was a firefox update after (120.1.0, build #2015989146), but same behavior. When opening accessing a new url (either new tab or existing tab). No message displayed, simply closes. Everything is up to date, non rooted galaxy S23 ultra with Android 14/OneUI 6. Already cleared firefox app cache, uninstalled and reinstalled (this worked for a few hours, but it's back to same behavior).

Any ideas?

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

For the past few weeks builds, downloading image from any website is weirdly triggering a crash of com.android.phone due to which mobile network is lost as well. Using Samsung Galaxy Note9.

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?

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!

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?

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?

I have an Iphone 11 Pro with iOS version 16.5.1, and I have been having some problems with the Firefox app. I have a number of tabs on my browser, with some of them being very old. I was trying to clear some of them up and I noticed that a good portion of them will not load. Even though I can see their titles in the tab, when I select them, only a blank white page loads up, not even with a URL bar, so I am unable to reload the site. When I try to tap on the tab for longer than a few seconds to bring up additional options, the whole app crashes.

What can be done about this?

Every time I open the current Firefox app it immediately opens and crashes. This starting happening a few days ago randomly but now happens all the time. I’ve deleted the app and reinstalled it but it didn’t help. Also restarted the iPhone 13 too. Suggestions? Thanks.

Hello Since few week I’m not able to use fiorefox on my iOS devices (iOS 16.5). The application is unusable :( it crashes in few seconds even if I don’t try to open new tabs. I tried to remove the app and reinstall again Firefox but without success at the moment I have the version 114.3. Do you have any suggestions on what I can try? I don’t know if this can help but Firefox focus and DuckDuckGo browser are working fine on my devices (I guess they share a good amount of the Firefox source code)

Thanks a lot Andrea

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

I posted a review on the iOS market and received an email asking to post on this forum.

Firefox freezes several times an hour. It crashes every three hours. I installed the Adblock Pro extension (free version). Maybe it’s related but I have not noticed anything related to the extension. Safari doesn’t crash and uses the same extension.

The only point to use Firefox on iOS is the password manager and dark mode. Printing is inferior because it forces pagination.

Hello everyone,

I'm encountering a persistent problem with my website when accessed via Firefox for iOS. The issue seems to be causing frequent crashes or instability when users attempt to navigate certain pages or perform specific actions.

Here are the details of the problem:

Browser: Firefox for iOS Devices tested: iPhone X, iPhone 11, iPad Air 4th Gen Issue: The website crashes intermittently when users perform actions like [specific actions causing crashes, e.g., filling out forms, clicking certain buttons, loading specific pages]. Frequency: The crashes occur frequently enough to hinder the user experience, impacting our site's usability. I have checked the website on other browsers and devices, and it seems to function correctly without any crashes. This leads me to believe that there might be an issue specific to Firefox for iOS.

I've ensured that the website's code is compliant with web standards and optimized for various browsers. However, I'm unsure why this problem persists solely on Firefox for iOS.

I'm reaching out to the community to seek advice, suggestions, or any similar experiences you might have encountered. I'm open to debugging suggestions, potential workarounds, or any insights that could help resolve this issue and provide a smoother experience for Firefox for iOS users.

Thank you in advance for your time and assistance. Your input would be greatly appreciated.

Since updating to the latest version, Firefox crashes constantly. All add-ons disabled, crashes on any website multiple time, crashes in Troubleshooting mode, crashes on restart. I've sent in about 10 reports today alone. Firefox is unstable and I'm unfortunately switching to Edge to continue to enjoy the web.

Hello!

Firefox for Android consistently closes whenever I try to play a video in full screen mode.

The steps to replicate this bug are as follows: I go to a website that has a video (like YouTube), I start playing a video, and then I click on the full screen button. Firefox then closes out to the main menu of the home. When I try to reenter the app, the Firefox app becomes a black screen with a horribly offset tiny corner showing a portion of the webpage.

I cannot find any crash reports in the "about Firefox" subsection of the settings

I am using The latest version of Android 13 And my version of Firefox is 114.2.0 (Build #2015957435). I have tried clearing the app cache, and reinstalling the app. Neither fixes it.

Please let me know if I can provide anything further!

Does anyone have any recommended fixes?

Every time I launch Firefox for iOS on my iPhone or iPad the app either crashes or hangs. I am using “old” Apple products both operating on iOS 15.7. Crashing occurs pretty much every time now I open the app (version Firefox 106.0 (20303)). I usually only have a handful of tabs open at any time so I don’t think my browsing habits are the cause? I have also noticed “flickering” between the shortcuts on my Firefox homepage - the name or icon for a few of the shortcuts switches around like some kind of identity crisis - so something is obviously glitching. The app hanging occurs when I am entering login/password details. Sometimes it takes 20 seconds to progress from the username field to the password field but more often the app just hangs and I have to relaunch and try again. I am almost at the point of ditching Firefox, the user experience is very bad. Any tips or suggestions please?
