I've been using Firefox for many years without a problem and have always liked it, but I've recently starting encountering a problem where Firefox consistently crashes after closing. After I close Firefox, the Windows Task Manager shows it still in memory. After a couple of minutes, the Mozilla Crash Reporter screen pops up informing me that Firefox had a problem and crashed, with an option to restart Firefox or Quit. I tried refreshing Firefox, which was a challenge because of the problem of hanging in memory after closing, but it did not resolve the problem. I also tried uninstalling it, then deleting the Mozilla folders and clearing out any references to Firefox in the Windows registry, and reinstalling it. I haven't installed any extensions yet; but sadly, I continue to encounter the problem. Any ideas about how to resolve the problem?

I should mention that I had bought a new SSD for my computer and migrated everything over from the old SSD to the new one. The problem with Firefox began after the migration. Everything else that was installed there works without a problem. I would be surprised if this is related to the issue considering I've reinstall Firefox.

Last Tuesday, Win 11 AND Firefox both updated on the same day, Firefox to 113.0.1. Ever since, my Firefox has experienced SIGNIFICANT lag time loading even the most basic of websites. It feels like Netscape 1.0 slow (yes, I'm that old). I've disabled 2/3ds of my addons to see if that would help and it hasn't. I don't know if it's an issue with the Win 11 update (KB5026372), with Firefox or some combination of both, but any help in addressing this issue would be greatly appreciated.

I been having problems with firefox using up most of my cpu while browsing some websites and it doesn't even load as fast as before. This has been happening for a few days now. Prior to this, firefox was fine and loading pretty quick, but these last few days have been painful.

Thinking that was a small bug, i restarted my computer. Before opening the firefox again, I opened up task manager to check how much resources will the browser be using. Before that usage would be normal and not even close to high, but opening firefox and waiting a few seconds to let the home window appear, the task manager showed that it was using all of it still.

I browsed some other help questions on this website and disabled "Use recommended performance settings", because that was one of the solutions on one of the relevant questions. But even that didn't do reduce resource usage either. Is there any way to fix this or will I have to suck it up and suffer with slow loading?

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

For the past few weeks, Firefox has started crashing when logging into various websites. I've updated Firefox, cleared cookies etc, reinstalled Firefox, opened it in Troubleshooting mode, updated my OS, disabled extensions... everything I can think of. After some sleuthing, it seems to only happen when trying to log into a website. Doesn't happen on every site, which is weird.

This is so frustrating, please help!

After updating from version 112 to 113 - performance has dropped dramatically.

In the beginning the performance after the update was faster than before. But as of tonight and today it's much worse than it was before the update.

I noticed that the browser started using more CPU than usual. Ryzen 7 5800X3D.

Cleaned cache already two times - didn't help. Tried Safe Mode - didn't help.

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

For many years I use Firefox 52.9.0esr on my WinXP computer. And for even more years I have been struggling unsuccessfully with the following problem.

Under "C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox\Profiles\2b9qepw7.default-1469870616368\cache2" there is a folder named "entries", that is constantly inflating! It is now 49.5 GB huge! I can not delete it. Deleting process does start, but doesn’t continue even for a bit or finishes ever. I’ve tried to delete the cache via Firefox preferences unsuccessfully. Even manually via Windows Explorer, even in safe mode (F8 when the computer starts), even with TotalCommander. The folder’s size just suddenly changes to zero when I click on it, but not the real space it’s occupying on my hard drive. I even uninstalled my antivirus and tried all the methods again – to no success…

I have added a video of what happens on my drive if I click on this folder in low resolution: https://drive.google.com/file/d/1E_gqf4s31m7Gr7taW5iUOUzkwe8Oi7iT/view?usp=drivesdk In high resolution: https://drive.google.com/file/d/1EaLROHC2p510CvP24nO83wplEkaAgrA9/view?usp=drivesdk

Please help me to solve this problem!

Thank you very much in advance!

I've had Firefox issues for months now. It started after the update three updates ago. Firefox would take 10-15 minutes to load, I often couldn't load websites even after it had loaded....except for a couple of nights recently I've been able to use it flawlessly. Like right now. It's almost 11pm and it's working. I've been through the clear the cache, check if the extensions are slowing it down etc. routine. So why is it working now? It probably won't work in the morning, it didn't work last night, but it worked a few nights ago and again tonight. I'm sorry this sounds so strange but I don't know what to do. I've had to use a different browser for a while but would love to come back to Firefox again.

I'm now running in troubleshooting mode with NO extensions.

For weeks my drives have been churning and I've been running out of resource, seeing the hour glass, graying screen, etc.

I finally closed the windows with countless tabs, disabled some extensions, and it got better, but I still have problems, even in troubleshooting mode.

Task manager still shows phantom tabs. I had 4 tabs open, it showed 7, etc.

And strangely, I now see Kaperski Native Messaging with the tabs in task manager: https://www.file.net/process/plugin-nm-server.exe.html

Closed that. Have 7 tabs in one window, task manager shows 11 tabs.

Am so confused.
