I have been using Thunderbird for years with no problems. However recently, Thunderbird very often simply stops responding. Sometimes it just hangs up and sometimes the program bar at the top displays "Mozilla Thunderbird (Not Responding)". If I try to wait for it to respond, it literally hangs for several minutes before it begins to respond again, and often, it simply never starts responding again. It has simply gotten to the point where Thunderbird is practically unusable. All my other application software continues to work with no problems. It's just Thumderbird.

The version number in this submission may not be correct. I can't provide the real version number because of the hangups.

Any suggestions?

Occurs since end February, so probably since 148.0-1 Always in the same place in libgio-2.0.so.0

I will try to roll back to 147.0.4-1

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

Dear Mozilla Support Team,

I have downloaded Firefox through the official website and I have installed it through the terminal for Chromebook's Debian Linux.

I have a Chromebook c214ma with a Intel Celeron 4020 with 4 GB ram every single browser on my machine works properly just Firefox keeps closing and crashing

Kindly fix this issue

Regards,

Pranav

I upgraded my Dell PC to Windows 11 yesterday via Windows Update, since support for Windows 10 is ending. Now Firefox crashes often when I close the browser. Everything works fine while I'm using Firefox, it's only when I close the browser that sometime later I will get a crash message on my desktop. I have tried uninstalling Firefox and reinstalling it, and the problem persists. From what I can tell, there's some process which is ongoing after the browser is closed, which isn't terminating properly and that's why it's crashing. I have submitted several crash reports, but don't know how to post them here.[bp-2e2d8f06-4c87-43a6-8b32-b0f5a0251006]

Immediately after I downloaded the latest update 153.0.1 for Firefox on the Mac, I noticed an issue with the Clear Recent History request. Whenever I select Clear Recent History (under History in the top bar menu), the popup box that opens always shows it is "calculating" the data, even if I only visited one website and closed it (or left it open). If the Clear button is active, I will click it and the box closes, but I never know if the history was cleared.

However, many times, the Clear button is grayed out while the "calculating" is in progress, and it freezes up the popup box. I cannot close it or click on any other part of the screen. It appears to freeze (crash) Firefox. My only option then is to quit Firefox and reopen it. When I do, the popup box is gone. But I still have no confirmation that the history has been deleted. But after visiting one or more websites that I want cleared of history (news sites, etc) the issue reappears again as soon as I select Clear Recent History.

I have a whitelist of many sites that I allow to store cookies and site data. But for all other sites, I routinely clear my history when I am done viewing them. This issue has never happened before, so I'm wondering if it is a bug in the latest 153.0.1 update. Before I downloaded the latest Firefox update, I checked to make sure it was compatible with my current version of Ventura 13.7.8 on a MBP 2022. And the clear history issue never appeared when I was on Firefox 152.0.6.

Attached is a screenshot of what the Clear Recent History popup looks like when "calculating"...

When playing a YouTube video and attempting to open a new tab, Firefox consistently crashes. This was also occurring with Picture-in-Picture mode.

Has anyone else encountered this?

I keep having an issue on my desktop of every new tab I open crashing. I can access the homepage, but if I put anything into the search bar, the screen goes to "Gah. Your tab just crashed. We can help! Choose Restore This Tab to reload the page." And when I try to restore the page, it brings me back to that screen again. I couldn't even access Mozilla Support on my desktop to report this, I am on this site through my phone.

My tabs crash all the time. Sometimes it'll go a while without crashing, other times it's literally every two seconds. Particularly if I'm doing anything that doesn't autosave. Thanks. Sometimes it's just whatever tab I'm on (or occasionally I'll click on one I've had open in the background only to discover it crashed at some point, other times (and not infrequently!) it crashes the entire browser. Sometimes when it does that, it also logs me out of everything for no particular reason as a little sadistic cherry on top. The passwords are still saved I'm just logged out of EVERYTHING. A few times, it seemed to have made my bookmarks go away, but force-stopping it and re-entering made them reappear, so they weren't deleted. I don't know what's going on but I'm at my wit's end. The crash reports mostly just say EXCEPTION_ACCESS_VIOLATION_WRITE (I haven't checked every single one individually since there's too many, but the ones I've clicked on all say that as far as I recall). If this keeps up I'm going to have to switch browsers or something because I'm actually losing it.

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?

Firefox crashes whenever my computer goes to sleep. I am running windows 11 and have been for years. This problem showed up a few months ago. The crash then screws up other apps and I have to restart my computer to fix it.

Hi, Windows 11, 32GB memory. Firefox crashes regularly when between 1.6 and 1.9 GB is consumed It happens when watching YouTube. What is the solution, please? Thank you.

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.

Firefox keeps crashing I've followed all steps, still crashing - memory / disk/ system/restart/troubleshooting I did have animaze installed but removed and still crashing

Above is latest crash report

I have used Firefox since version 1.5 and have loved it and the community since. However, since finally scrapping Windows and switching completely to linux, Firefox has been frequently troublesome with random crashes. The crashes occur on any website I may be on and for seemingly no reason. It happens when I'm in the middle of browsing a page, just opened a new tab, or even when Firefox is simply open and I'm active on another open application.

Environment is as follows:

OS: Zorin OS 18 (Latest patches) (Based on Ubuntu) Mobo: Asus Crosshair VI Hero (Latest available BIOS) CPU: Ryzen 9 5900XT GPU: EVGA GeForce RTX 3080 XC Gaming (10GB) Ram: 8GBx4 G.Skill TridentZ RGB DDR4 (3200) Sys Drive: Samsung 970Evo M.2 Nvme 500GB

Firefox is installed via Flatpack through the built in app store in Zorin OS.

The crashes will sometimes be constant as well. Such as when it crashes, crash reporter comes up, then I click "Restart Firefox" and the second I see the window, it crashes again. This has been a constant problem though at random times ever since I switched back to Linux about 5 months ago.

Any help would be greatly appreciated. I don't want to have to change my primary browser from one that I am generally so happy with, and is also the browser that I recommend to everyone.
