I have just reinstalled Windows 10 and now I cannot see my old firex=ox history from prior to the reinstall of Windows 10 Is there a solution and also i downloaded firefox and now every tab crashes immediately

My firefox has been closing while I am away from my computers. I have a few computer running linux (Ubuntu 24.04) and one in mac osx (Big Sur). Usually, I can start firefox and it will remember my tabs which is annoying but still manageable. However, once in a while, (which happened yesterday), all the firefox closed on all the computers and it forgot my tabs when I start firefox again.

I have already set app.update.auto to false on all of the firefox instance prior to this incident to avoid firefox update would close out firefox itself. So if anyone has any idea of what to check to see why firefox keep closing and/or why once in a while it will not remember my tabs, I would really appreciate it.

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

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 ?

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.

Hello,

I would like to report a potential bug in Mozilla Firefox related to recent updates.

After downloading a PDF file and opening it directly in the browser, the tab crashes. Following this crash, it becomes impossible to open any files (regardless of file type) within the browser — every attempt results in another tab crash. The crash report cannot be reviewed, as the tab fails immediately and can only be closed.

As a temporary workaround, changing the default PDF handler to an external application prevents the issue. However, this is not a viable solution for us, since some of our internal systems require PDFs to open directly in the browser after download.

We have verified that this issue does NOT occur in version 148.0.2 — everything works correctly there. However, after updating to version 149.0, the problem reappears consistently. Firefox also automatically updates after synchronization, making it difficult to remain on a stable version.

According to the release notes, there were changes in PDF handling in recent updates, so this may be related to a technical regression.

Could you please investigate this issue or advise on a proper fix or workaround?

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,

I don't want to spend any more on my PC. It was the largest amount of money I had ever seen when I first bought it. Even if I have way more resources now, I don't believe that a few faulty locations in my memory should be causing so many problems for myself and for developers who have no clue why their users keep crashing.

It is either my RAM or VRAM. Disabling XMP on my RAM dampened these issues but couldn't fully solve them.

It's exactly as I said. Normal programs just crash. Kernel-level programs or anti-cheats can entirely blue screen my PC. It all has to do with where these programs are writing to in my hardware. It's only a few locations that I have faulty. Most programs work fine. Most games work fine. Most crashes are very transient.

Firefox is a transient and common crasher for me. It's so painful to be scrolling a page and have the page crash, just for the previous page to load instead of the newer one that I was on, and on top of that I could also be losing work or effort.

I know this isn't exactly a dev support page, but this problem is so recurring that I don't know what to think anymore. There has to be a way to check which memory locations are fried without causing a bluescreen or crashing the program. Maybe it's a Windows issue and devs could easily fix it, if it weren't for Windows bottlenecks like labelling the faulty locations as "protected". I've seen at least 1 crash where the output said something like "Error: tried writing to protected location" blah blah blah then it spit out some hexcode or exact location and blahblahblah. And that was the entire error message.

Firefox keeps shutting down and it will open up when I tap on the icon. I have to reload it to make it work, It seems like I have to do this everytime I shut the pc.

for years now I have had this issue when browsing. It is so annoying. I have tried all the suggested troubleshooting. I deleted all extensions. This helped for a while, but not for long. Now it's so tedious to browse that I am thinking of getting rid of Firefox. It has just become unusable and no one can seem to fix it. I am using Windows 10 and no extensions. It often happens when I first open a page and while the page is being pulled up.
