Firefox Community Forum

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

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"...

All the tabs, in both my profiles are constantly crashing. I cannot keep at a task for more than a few minutes without needing to restart the tab. Is this a setting problem? I've cleared the cache, and reset Firefox, to no avail. Thank you for any relevant advice and/or assistance.

• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

Firefox is CONSTANTLY crashing now and I'm about ready to switch to another browser unless someone can give me a reason to stay.

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).

Since the 152.0 update I've experienced near nonstop browser crashing, it crashed twice as I was trying to type up and submit this message,

Is this a known issue or solely on my end? running 64 bit, windows 10

I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

Firefox keeps suddenly crashing, I have reset Firefox, deleted it and reinstalled it, I have used DISM and SFC to repair any issues and I have set up a new profile within Firefox with no extensions, but still I have the same issue, either tabs suddenly crash or the whole Firefox does.

I've been using Mozilla Firefox browser for the better part of the last two decades, having always found it to be the most functional and useful over all competitors, who generally seem more interested in raising revenue or spewing puerile and slanted politics. I've been accustomed to the occasional "crashes" and always provided input when they occurred, convinced that the interruptions would be brief and with any issues resolved. Today was different.

Lately, my processor was experiencing some "aging" issues: slowdowns, freezing forcing me to re-start, and random re-starts on its own. Over the weekend I conducted a comprehensive series of diagnostic tests of all features of the operating system. To my relief, the system went back to normal and efficient, including the browser -- for about 2 days.

Early today the browser became slow, eventually inactive, and ultimately crashing 7 times. But all these time were different: my input into the "crash warning box" was not permitted and closing the box only resulted with the next crash. All crashes had the same reason posted on their reports: "Crash Reason EXCEPTION_ACCESS_VIOLATION."

When the crashes finally ended, my browser looked totally unlike it did before:

(1) ALL of the shortcuts I entered on the home page and relied upon for years VANISHED. (2) ALL of the browser windows and the open tabs I was working through at the time EVAPORATED. (3) ALL extensions I saved and used routinely GONE.

By the end of the day, one spent trying to resurrect "my" Mozilla browser with minimal damage, something else disconcerting occurred: the processor's operating system randomly shut and re-started. I don't want to point fingers just yet and allege this was connected with my browser failing, but the coincidence is troubling, one I would recommend looking into. My assistance is, of course, automatic.

Hello, Whenever I open Firefox, it crashes repeatedly. This has been going on for at least a couple of weeks, whether it's right when I open it or hours later when I'm in the middle of something. I've disabled extensions, ran it in troubleshoot, and done the steps advised to no avail. Any help would be greatly appreciated as this has rendered Firefox unusable. Attached is a screenshot of the digits of the crash reports, as well as the link for the one from today.

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.
