Whenever I’m in a tab where I searched something and I click the three dots the app crashes and closes making it impossible to save bookmarks and etc when having a tab open. But when I’m on the home page it works fine. This is only a problem on my iPad since I first installed the app. My iPad is on the newest iOS update and so is Firefox, also have the latest iPad.

I'm getting a lot of crashes lately. I've restarted my phone, force closed Firefox and deleted the cache. Didn't fix it unfortunately. Firefox Android Mobile 134.0.2 (Build #2016068999)

Here is the error: 95dfeae4-16a9-45bd-8474-02ede37eb9dc java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

エラーメッセージ「Thunderbirdは起動していますが応答しません。新しいウィンドウを開くには、既存のThunderbirdプロセスを終了させなければなりません。」　が出て起動できなりました。ネットを参考に・システムの再起動やトラブルシューティングモード起動など試してみましたが、同じ結果でした。 これまでThunderbirdを利用させてもらって、大変助かっており皆様には感謝いたしております。今回は初めてのトラブルでほとほと困っております。 どなたか対処方法や参考になるサイトなどがありましたら、お教え願いますでしょうか。よろしくお願いいたします。

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812

Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

For over 1 week now I am finding that T-Bird freezes or locks after I have opened several messages. Leaves me unable to read or delete messages and unable to close down T-bird

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

If there's one thing I can count on, it's that the next version of Thunderbird will be more buggy & unstable that the previous version, and v 140 certainly does not disappoint in that category. It crashes & closes multiple times per day. Any time something else may be using a lot of resources, Thunderbird freezes up and if I click on it, the app crashes & closes. At least the previous just stayed greyed out until it was able to complete the task and didn't crash & close. Great job Mozilla.

My mobile app Firefox keeps crashing on starting it reinstalling doesn't help it used to work at some point but now it doesn't.

My phone is OnePlus 13 it has the latest EU updates. I can't seem to figure out why it crashes.

I installed the latest version from the Google play store. Other versions of Firefox work fine like nightly or beta only the main one crashes.

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

Hi all, I'm experiencing persistent and reproducible segmentation fault crashes with both Thunderbird (versions 140.0.1, 141, and 142 tested) and Betterbird on Arch Linux. The crashes occur consistently within 30 seconds to 2 minutes of operation, making the application unusable.

System Configuration:

• Arch Linux (fully updated)
• KDE Plasma 6 on Wayland
• Multi-monitor setup using DisplayLink/evdi drivers
• Firefox works perfectly fine (no crashes)

What I've Already Tried:

• Fresh profiles (completely clean - crashes persist)
• Safe mode with add-ons disabled
• Disabling hardware acceleration (MOZ_DISABLE_RDD_SANDBOX=1, --disable-gpu)
• Software rendering mode
• Multiple Thunderbird versions (140, 141, 142)
• Alternative client (Betterbird) - same crashes
• Full system upgrade

All crashes show the same signature in libxul.so during startup/operation. The stack traces consistently point to Mozilla's threading/compositor code. Notably, Firefox using the same libxul.so library works without any issues, which suggests this is Thunderbird-specific.

I believe the issue is related to KWin compositor interaction with my multi-monitor DisplayLink (evdi) setup on Wayland. The crashes are specific to Thunderbird/Betterbird and do not occur with Firefox, despite them sharing core libraries. Note that this problem happens on both x11 and Wayland.

I have extensive coredumpctl output available if that would be helpful for debugging. Has anyone else experienced similar crashes with multi-monitor setups or KWin/Wayland compositor issues?

Any assistance would be greatly appreciated!

With thunderbird version 140.4.0esr (64-Bit) on Linux functions to print e-mails or pdf documents is no longer working. When trying to print an email or a pdf document thunderbird starts looping and you need to stop thunderbird from outside with a kill command.

I'm using Win 11 and ver 140.3.1esr (64 bit)

Thunderbird works perfectly except for just one thing. Every time I write any email it freezes after about 2 minutes. If it's a short email, it gets sent. If it's longer, before I can get to the end, the program freezes, and I have to use Task Manager to stop it. No problem receiving and reading emails. This started about a month ago.

I use Bitdefender, but it still happens with that off. Windows is up to date. Any ideas why this is happening? Thanks.

Getting "Mozilla Firefox Crash Reporter" problem message when attempting to print files (Docs & Sheets) from Google Cloud. Errors messages have appeared on Lenova Thinkpad laptop in Firefox since mid Dec update. Can print existing files located on desktop, just not from cloud. Both HP and Epson Printers test fine, can print 'test pages'. Tried downloading files from cloud to pc....opening downloads, got same Firefox problem message and crashed. Have used same firefox browser and same printers for several years. Rebooted several times, same error. Can print, 'printer test pages'. Do I have a switch turned off/on or is this a browser problem. Any assistance would be appreciated.

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

When I attempt to add an attachment, sometimes Mozilla crashes. This happens several times a month. Windows 10 Home "File Explorer" pops up & I can be scrolling and it will crash Mozilla. Other times I am selecting the file to attach & it crashes. I am at a loss as to why. I'm using the latest version & "Send later" is my only add-on.

143.1 updated onto my app this morning and now the app refuses to load. It opens for a second and sometimes begins to show the browsing interface and then it immediately crashes. All subsequent attempts to open the app have failed. I've deleted and reinstalled the app and restarted my phone and that has not fixed the issue.

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?
