Hello everyone,

yesterday I got quite a scare. While Firefox was open, a new tab briefly appeared showing the page about:processes, and immediately afterwards the browser closed itself on its own.

At the same time, Chrome was open in the background. When I clicked on Chrome, a prompt appeared asking whether I wanted to allow changes to be made to the system (the typical UAC prompt). However, I’m not entirely sure if this was actually triggered by Chrome or possibly by another application.

I clicked “No” on the UAC prompt and immediately unplugged my keyboard. I recently started using an ASUS ROG Falcata, which is connected via USB.

After that, I ran a virus scan with Windows Defender — it didn’t find anything. I also ran AdwCleaner, which also came up clean.

At first, I suspected the ASUS ROG Falcata (I’ve only been using it for a few days), since it’s almost like a small computer itself and can execute macros, patterns, etc. I was worried about a possible firmware bug or something worse. At the moment, I’m honestly hesitant to plug it back in and am using an old Dell keyboard instead.

Importantly, I wasn’t pressing any keys at the time of the incident.

Now I’m quite unsure what could have caused this.

Is there any way to trace this in Firefox (e.g., via logs)?

And is there any (event) log where I could check what triggered the UAC prompt?

One more thing I noticed: I shut down the PC afterward and turned it back on later that evening. Everything booted normally and is still running fine today. However, Firefox updated itself yesterday from version 148.2 to 149. Maybe that was somehow related (though there’s no indication in the Firefox update history that anything failed or similar).

I use Linux Mint and I have been experiencing numerous system crashes involving Firefox which requires a cold boot. What is the problem? How can I debug this? Are you getting crash reports?’

This happens several times a week. It has happened continuously tonight since installing the latest update via the Software Manager.

The program causes a total freeze of the OS. All other running programs and all input sources. I have no choice but to shut down via the power button on the tower.

Mint generates crash reports but I have no way to determine if they are being sent to Mozilla.

Firefox for Linux does not provide a troubleshooting system like it does on Windows. Neither does Mint.

I studied Computer Science in the 80s when Firefox was known as Navigator. I learned C and the Unix OS, but since then I became a psychologist, and don't remember too much of the Com Sci stuff I learned and I don't think Mint allows user modifications anyway.

What can be done to fix this? I don't have the Benjamins to buy a new Windows to replace the Linux, nor do I want to.

I have followed all the other recommendations with, no luck. I am on Windows 11 and use Eset virus software. Thunderbird is not listed as running it Task Manager, and there is no Profile.lock (think that was what it was called) in the profile directory, and I have deleted the existing profiles and recreated it. I have uninstalled and reinstall Thunderbird, and I have rebooted my computer. I am frustrated and concerned I will loose saved emails and my address book! Help.

After updating to 150 (any subversion), FF crashes on almost start - I can load a page but loading another page or a video in the page will stop loading after a while and crash within 5-10sec. No about:crashes generated. No crash if I only browse the page that's opened (except if I load extra content like videos). FF remembers if I navigate to another page before the crash, it'll open the navigated-to tab (provided it has been long enough, small pages load, big pages don't). It really looks like after loading a fixed amount of data it just stops loading and crashes, taking the full browser down with it. Note that there is likely 500+ tabs opened (even though it's never been a problem), cache was cleared and extensions deactivated.

For the first time in many many years, the beta's unstable (brillant track record for a beta)!

why im cant set www.http//firefox for home page.??why we have to re store evetime when we washing a movie,,,then they automatic to ture off ?are they have any shearch with out of the google ?

As the subject says, Thunderbird 18.0 for Android keeps crashing silently. There doesn't appear to be any specific trigger; periodically, the app just disappears off screen. Since it doesn't seem to be related to a specific user action, I wonder whether a background process (such as server syncing) might be causing it. My device is a Samsung Tab A-9.

On a samsung a54 running android 16 and thunderbird 18.0, thunderbird crashes on trying to open a specific email from theglobesailer.com. it does contain quite a lot of images? Interestingly, it opens ok on my tablet running 17.0. I can't see anywhere obvious to submit a bug report, so maybe someone on here could pass it on, please?

why does my fire fox keep crashing the screen goes black i get tab just crashed already updated and cleaned my ram and did everything i could think of and still crashing am still crashing on troubleshooting mode

I am running Fedora 42 KDE spin ("plasma"). The "Discover Software Center" app offers Thunderbird as both a regular and a flatpak install, and I somewhat arbitrarily chose flatpak.

I am dealing with several legacy email accounts that have 20 years of messages, so I need to control where the profile was created, so immediately after installing I ran with -P to create a profile and specified a path name of /lore/jeff/thunderbird. /lore is the mountpoint of /dev/sda2 and it is in my /etc/fstab. /lore/jeff previously existed because that's where I put my Dropbox folder.

Every time I shut down TB and restart it later it always fails because lock and .parentlock are never deleted. Until now, I just dealt with it by deleting the files in bash, but today I wanted to make sure that TB always starts offline and decided that user.js would be the absolute safest way to guarantee that, so I pulled up profiles.ini to get a list of all profile paths to make sure that I put a copy of user.js in each and every one whether it's in use or not. What I discovered is that the profile I created does NOT have a Path of /lore/jeff/thunderbird but instead /run/user/1000/doc/e1a4ab74/thunderbird and not only that but at the very bottom of the file are these three lines [InstallBD520B11F73A6B64] Default=/run/user/1000/doc/e1a4ab74/thunderbird Locked=1

The interesting thing is that when I put user.js into the /run/user... path and then looked at /lore/jeff/thunderbird to check on lock and .parentlock, I see that there is magically a copy of user.js there. I'm not exactly sure what is going on because when I do `ls -ldi` on the two files, their inode numbers are vastly different. I don't know enough about how flatpak operates internally, but my gut tells me it has something to do with it, and my question that I'm finally getting around to asking is if I edit the profiles.ini file to use /lore/jeff/thunderbird in an attempt to get TB to correctly clean up the lock files, is that going to cause a problem because of whatever flatpak is doing? And should I complain to flatpak about it?

Thanks for reading :-)

After the most recent Thunderbird app update from Google play, the Thunderbird app crashes instantly and constantly on start up. I did restart, uninstall, reinstall, OS update, clear cache, smart clean and still the Thunderbird app crashes instantly on start up. The screen will flash a few times as the app attempts to start. But instantly a window pops up saying the app has unfortunately shutdown. I am at witts end. I have been using Thunderbird for years. Never had this happen before. Anyone have any ideas? Google suggests getting hold of Mozilla support because this is becoming an on going issue. Please help.

Okay. So I downloaded Firefox on my chromebook from flathub, but it keeps crashing. I open a new tab: it crashes. I close a tab: it crashes. I don't open or close anything: it crashes. I don't touch anything: it crashes.

I've says that either my theme or one of my add-ons is causing the crashes but I removed my theme and it still crashes and I can't remove any add-on because it crashes if I try to open a new tab.

Now, did/does anyone else have this problem or am I just stupid and missing a very obvious thing.

my firefox keep crashing when i join google meet and i need to do multitask so i open another firefox windows(private or not) it always crash few second after, i have tried the trouble shoot mode its still crashing, even the new windows from SSO request do trigger my firefox to crash. when the browser crash it does offer me to restore my session

Hello -- I'm hoping someone will be able to help!

I'm running Thunderbird 140.9.1esr (32-bit) on Windows 10 Pro version 22H2 (OS Build 19045.6466) with an Intel Core i7 processor.

Thunderbird suddenly started crashing repeatedly since yesterday. It ran long enough for me to install version 140.9.1esr, but still crashes repeatedly within a couple minutes of running the application, even if I don't do anything such as trying to reply to a message.

Please see below what I get in the Windows Event Viewer, pretty much the same for each crash. I have also pasted the contents of the following file (the others mentioned above don't exist).

C:\ProgramData\Microsoft\Windows\WER\ReportArchive\AppHang_thunderbird.exe_5d8d3f9d863d0b28eacbd2a393cdc3d04ef559_c250478b_deffcb88-26f8-4204-bffd-7e6fd5a2ea88

I've gone to Troubleshooting Information, I've "cleared startup cache", I've tired "Troubleshoot Mode" and still Thunderbird crashes. There's nothing in Crash Reports.

Any help would be truly appreciated!

Best regards,

Miles Montelius

Every time I open Thunderbird, I get the attached pop-up which I can't delete except when I use control alt delete. It always comes back. How can I permanently delete it? Thanks, Mark

The dialogue box says "The application is exiting and cannot service this request"

Nonetheless Firefox seem to be functioning as I would expect apart from the irritating appearance of the dialogue box that I have described.

I attached a scan of the dialogue box - how do I prevent it appearing and/or is it signifying anything important,
