Hi all,

Firefox is crashing when launched, but not all the time. After a couple of tries, it will launch without issue. This is a brand new Windows 11 Pro installation with all updates. I have run some windows debloating scripts like privacy.sexy and WinDebloatTools, thinking that might have something to do with it, but not sure where to start in troubleshooting this. Any help with where to start looking would be great. Thanks!

Hi there, like it says. My firefox crashes immediately upon trying to play a video. Even simply scrolling over a video on youtube or google results, it breaks when it tries to the preview. This is the same on Twitter, Facebook, Campus Moodle, etc. Every website I use.

I've had this problem before and I did fix it by totalling wiping my history and browsing cache. Doing that and having to sign back into everything is super tedious though and I don't want it to keep happening. This doesn't happen when I use firefox's troubleshooting mode, everything works as normal and videos play without the browser crashing. So I think it must be something specific to my browsing history somehow? But I've no idea how that could crash the browser just from trying to play a video.

The browser started continuously crashing a few days ago. When I reopen the app, a message pops up that says it crashed and wants to know if I want to reopen all of my tabs or not. The app will almost immediately crash again. Sometimes there’s enough time to hit yes or no on request to reopen the tabs. Regardless of what one is pressed, the app almost immediately crashes once more. I checked the app, and realized I was using 107.0 instead of the most current 107.2 app. I updated the app, and I made sure I was using the most current iOS as well. I’ve restarted my phone. I’ve deleted and reinstalled the app, but to no avail. Is anyone else experiencing these issues? Please help?

This appears to be a problem that others have had (with no response). I'm posting it to let the Mozilla team know it continues to be a problem for some users.

Yesterday FF (whatever the latest version is running on an iPad Pro running iPadOS 15.7) crashed, and restarted with the usual "This is embarrassing..." message, and asked whether I want to restore all tabs. I hit yes, and it restarted with all tabs missing. Of course it then proceeded to erase all synced tabs the next time it connects to Mozilla's servers, so now all the tabs are gone.

Questions:

1. Is there a way to restore this to its previous state? As far as I can tell, the moment the mobile FF loses all its tabs and syncs them to the cloud, there's no easy way for the user to get the old tabs back.

2. Is it possible to have Sync set up so it doesn't erase all the tabs automatically? I mean, it should be clear that when this occurs after a crash, this may not be the desired behavior. At the very least, there should be an option to undo.

3. Is there a way to just "bookmark all tabs" on mobile FF? That way users can easily save the current state of their mobile browser without having to bookmark each tab individually. I understand this feature has been requested from time to time, and at some point saw a response from a Mozilla engineer saying it has been implemented but not released for UI reasons.

4. Can I download all my Firefox Sync data? Since Sync seems to write over previous state with no method for recovery, it cannot be relied upon as a backup. I would like to be able to make my own backups of my browser states to the extent I can.

Thanks! In principle I support open source and would like to continue using FF. If these usability / reliability issues can be resolved I think it would make at least a few FF users quite happy.

These "crashes" aren't in the Report, so I'm not sure what to do. I've pressed Quit, I've cleared the Cache (twice), and I've deleted and reinstalled the app. Firefox was working just fine until recently. These crashes only to seemingly happen on YouTube and Tumblr. It closes worse when I have the YouYube in Background Add-on on, but it isn't just because of that. If anyone knows how to fix this, feel free to answer.

since the last redevelopment of Mozilla Firefox I am having trouble exiting both my private and non private browser. I want to uninstall Firefox and re install it to see if that gets rid of the gremlins.

I have being using this particular browser for a long time. It worked for me very smoothly. However, since in the recent past I was faced with bad browsing behaviours. Delayance,crashes, and failures among others. Kindly advise?

I did what you told me to resolve the problem. Didn't work! It's probably some barf sack of government shit creature stealing control over my machine, that I pay for, like the rest of these fuck from hell Canadian life stealing, life wrecking, life sucking Canadian intestinal worms I hate more than Satan hated Christ. That like stealing control on MY LIFE after I voted this country, government and people the fuck out of my life with their forced fuck from hell canadian citizenshit at the federal and provincial elections. Along with this shit world of shit people and it's faggit shit mutations that I want crucified. Just whose life is it anyway. Because it sure as to hell ain't mine.

I have a iPhone 13 running iOS 16.2. I have Firefox 108.1 running on it. Yesterday it starts to crash on launch. Can’t even get to troubleshooting. Immediately shuts down. I have already uninstalled and reinstalled multiple times. Tried turning off sync still crashes. Any ideas would be appreciated

Firefox crashes with the same issue as before (https://support.mozilla.org/hu/questions/1395270), but with two minor differences. I'm now using the latest version of ExplorerPatcher and Firefox works fine in safe mode. I tried disabling all the add-ons, themes and extensions in while in safe mode and then launch Firefox, but it didn't work. The developer made the issues and discussion sections read only on the project's GitHub page, so I'm unable to contact them. Here are the logs about the most recent crashes:

• bp-b22c808e-b212-4c4e-9f11-c0d120221105

I’ve been using Firefox synced to my account on my iPad for a while with no problems, and only started running into this problem today. The app for the most part works normally, but when I open specifically the history tab the whole app crashes. I can still use Firefox on my android and computer completely fine, and have tried clearing some of my history using my phone, to no avail. Only the history tab does this- downloads, bookmarks, and reading list are all fine. Any advice on how to fix this?

After the most recent update to version 106.1 on my iPhone 11 iOS 15.6.1, every time I open Firefox and open a new tab the browser is unresponsive for several seconds, then slowly registers my input in the search bar, and occasionally crashes during that process. It also hangs up and crashes at random. It will no longer open links to PDF files. I love Firefox, but this is becoming unusable.

I am regularly getting crashes on Firefox When browsing using my iPhone 12 mini running on iOS 16. As soon as there is any sort of ‘heavier’ task, such as loading a PDF or browsing an online news site with loads of ads, the whole browser just freezes up and I can’t do anything unless I force close the browser via the multitasker.

It is happening multiple times per day.

What information can I provide to you to help troubleshoot this issue?

After a Firefox update the app stopped working. It crashes all the time when being open.

Firefox asks if I want to restore tabs, but no matter the answer it always crashes. I did reinstall the app on the phone - did not help.

Here is the video of two consecutive crashes: https://youtube.com/shorts/lHyN8Lq1GBY

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.

Hey, Since I've updated my ipad to the newest os (15.7) my Firefox got really slow and buggy. Often it simply crashes once it's loading a page. I am not be able to use my enpass password manager anymore too... It simply won't show the keyboard once I want to log into anything. A look in the reviews section of the app store shows me I am not alone.

What's going on? I am using Firefox on so many devices but not on my ipad it's just not usable anymore.

Thanks in advance for help .
