Firefox Community Forum

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.

A few moments after opening Firefox, (on an Acer Spin 5 that is up to date) Il loses connection along with all other Firefox open tabs, all on its own. When retrying on Firefox, a message appears saying that it is unable to retrieve the prior session. What is causing this and how can it be fixed?

When I open Firefox for the first time after logging in to my macbook, after a few minutes, a second Firefox icon appears in the dock at the bottom of the screen. Why is this happening (only started a few days ago)? And how do I stop it?

Browser shuts down within 10 -20 seconds of going to a website, and I get a crash report which I have clicked to forwarded each time to Mozilla.

Also have a new error message at the top of the browser that says: "The security sandbox is disabled. Your configuration is unsupported and less secure." (image attached)

Not sure if that is related or not.

Dragging and Dropping folders to upload on dropbox.com have worked flawlessly before Firefox 150.0

Now in Firefox 150.0, dragging and dropping a folder will result in the tab crash.

See attached image of the notice.

Note: This tab crash does not produce a crash report as nothing is shown for this tab crash on "about:crashes"

Been having tab crashes every couple of minutes - doesn't matter what the site is, the tab will crash out and I'll have to refresh. I have a laptop that is synced that I also use that doesn't have this issues - it's isolated to the PC.

Tried sfc, DISM, hardware and memory checks - all come back good. I'm inclined to believe it could be something on the operating system and not hardware, but I also recently reinstalled Windows. I had another thought that it could be something with JavaScript (seemed like a common theme in the error reports, but I'm not 100% what I'm looking at or for).

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 experiencing significant stability issues with Firefox. When I use YouTube, the entire browser frequently hangs (becomes unresponsive) and eventually crashes. This does not happen on all websites, but it is consistent when playing video content on YouTube.

• Symptoms: The browser "stacks" or freezes completely; I cannot click tabs or menus until the browser finally closes/crashes.

• Extensions: I am currently using extensions like SponsorBlock, uBlock origin. I am unsure if this is the cause, but the issue persists during video playback.

• Hardware: I am running this on a laptop with an 16gb 4800mhz RAM, i7 12th Gen processor and an RTX 3070 GPU.

1. Is there a known compatibility issue between current Firefox builds and SponsorBlock or similar video-modifying extensions?

1. Could this be related to hardware acceleration settings with my NVIDIA GPU?

1. What steps should I take to provide crash logs to help identify the root cause?

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.

I am not a computer nerd I can only describe what is happening. I am addicted to puzzles and do them every day but am encountering problems nearly every day this week of the puzzle pieces not responding to mouse and have to shut down the computer. At other times I am kicked out of the site and returned to my desk top. No amount of trying to then get back into firefox is useless until much later on. Why is this happening?

Hello, Firefox has been giving me some troubles lately and I can't figure out how to resolve the problem. Since I haven't found any way to consistently reproduce crashes, it is very hard for me to tell if Troubleshoot Mode also experiences the crashes, and the time I can spend doing that is very limited. As previously stated, it is very inconsistent, but relatively frequent, sometimes it crashes very soon and several times in a day, others it doesn’t at all. Sometimes it crashes with several tabs open, sometimes with only one; sometimes it crashes while using a webapp, others it does so on the newspaper page. It might be more frequent while there are Electron Webapps open, but it's more a hunch than anything, since sometimes it happens without those. I have followed the steps in: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-crashes-closing-or-quitting Been unable to find the cause so far. Here is the crash report ID from the latest crash: bp-60cd6ea9-9bd1-411d-a0ca-2f6fd0260415

The crash report does include information on my system, but please let me know if any other information might be useful.

Thank you very much in advance and I hope you're having a great day.

I face an issue with the browser crashing when in google meeting (meet.google.com). The problem persist in a new profile created with 'firefox.exe -P' and also in the troubleshooting mode. The crash is triggered when I am in the google meeting (with allowed microphone) and I manipulate with windows of the browser - across multiple monitors (switching tabs, moving tabs between windows, closing firefox windows, opening them, "dropping" the tabs onto another applications - chrome, spotify - which opens a new firefox window). Sometime the crash happened once I closed the google meeting tab. Unfortunately it happens "randomly" and I was not able to come with a specific series of steps to reproduce the crash. But it happens always when I am in the meeting and play with the windows for a while.

The crash: Firefox freezes for a few seconds (~3s) and then closes itself - all windows. %appdata%\Mozilla\Firefox\Crash Reports\pending contains a new .dmp file, but it has 0 bytes and no .extra file is created, hence it cannot be submitted via about:crashes. The crash reporter is not opened when firefox crashes. The attached troubleshooting information are from the new clear profile where the crash happens as well.
