Hi, Once last week I had Firefox crash, like quite literally the window I had open just closed abruptly. Tried doing the refresh using the setup wizard and it did not help. Then I've tried uninstalling/reinstalling several times. Each time it'll open up like new, and within 10 minutes the window closes randomly and then Firefox doesn't launch anymore on my laptop. No error message, just does not launch whether I try to from taskbar or Home or even run as administrator. Seemingly random I've been using Firefox for months and it just started doing this last week.

Sorry for lack of other info, thanks for any help you're able to give.

Когда firefox зависает и windows предлагает его убить, firefox получает права системы и по этому становиться не убиваемым.Система не может его убить потому что у его права системы .В первые заметил этот баг когда сделал браузер firefox браузером по умолчанию.У меня сим роутер при запуске системы открывает браузер тут та браузер и зависает (не всегда ,но часто) в диспетчере задач в этот момент у его права системы.Писал в майрософт ,майкрософт посоветовал пользоваться нормальным браузером и сменить браузер по умолчанию .По совету майкрософт сменил браузер по умолчанию на chrome проблема пропала. Firefox 140.0.2 (64-разрядный) Windows 11 версия 24H2

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

Firefox has stopped working about 5 times in the last few days while browsing? sometimes on Youtube sometimes it just completely freezes and wont even close with task manager I had to force my pc to reboot yetserday because it wouldnt respond, my pc is rock solid stable while doing anything else including gaming and is 16 months old and have never crashed even once???

Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

Firefox has recently started crashing multiple times per day. The crashes do not seem to be website specific.

Here is a list of my submitted crash reports. Please help.

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

Hi Team,

When we enable Netskope, all the searches breaks (specifically with Google Search Engine). It takes about 2 to 3 mins to do the first search, after which it continues to work normally.

Furthermore, facebook takes too long to load (~4mins).

The netskope support team has asked us to make a few changes in about:config: 1. network.http.http3.enabled 2. QUIC protocol 3. network.udp.enabled

None of this works and even if it works, the problem is we have about 1500 devices.

Are there any reported issues ? And is there anything that we are missing ?

I have noticed a weird scrolling bug in Firefox since either v138.0 or v138.0.1.

If you go to https://www.architecturaldesigns.com/ and select any floor plan, if you attempt to scroll down the page the page will not let you and snap back to the top.

I tried this in Firefox troubleshooting mode with all add-ons / themes disabled and encountered the same behavior. This is something that just started happening in the last version release or two.

This is present both on Windows as well as Mac versions of the Firefox browser.

From the last two Firefox updates, I no longer can move sites screens around on my Mac Air laptop. Only one page at a time shows up and consumes the screen. I am no longer able to copy and past and move info to another screen. A couple of weeks agom I cleared my cache but not sure that had anything to do with it. Please suggest solutions. Is there an add on or something that needs adjusting?

Thank you.

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

When I open FF 137 on my iMac running OS 12.7.6, it just keep trying and trying with no link. When I try and quit it needs to be forced quick to stop running. There are no fire walls and it worked yesterday 4-5-25 just fine, but no go today. I tried replacing FF and still no luck, what do I try now, [email removed]@yahoo.com

I recently updated my Firefox browser from version 136. to version 137. and after the update I was unable to get online to any website I tried and Firefox would freeze and crash, generating a crash report that Mozilla probably didn't get because firefox couldn't send it. Safari was working, as was Chrome, so I know it wasn't a network issue. I cleared the cache and tried again and still nothing. I then uninstalled Firefox and reinstalled it from the Mozilla website, (had to use Safarii to get the Mozilla website) and still could not get to any websites. I'm on a Mac runnning OS 15.3.2 and I have a bootable backup of my machine that still had a copy of Firefox v 136 which i reinstalled on my mac and it works. What can I do to update to 137?
