Occasionally, any piece of complex software will stop responding, and need to be forcibly shut down. I had such an event today when the right-click (context) menus and title-bar menus wouldn't appear. However, since upgrading to FF 57, I now see about 6 Firefox tasks and 6 firefox.exe processes in the Task Manager (Windows 10).

I like the feature of being able to restart Firefox (after killing it) and have my previous session restored, but the processes aren't really distinguishable in Task Manager, so I don't know which one to end/kill. I had to kill a few of them today before I stumbled upon the "main" process and Firefox disappeared. Can you help me to identify the main process for next time?

Firefox automatically upgraded to 5.7. It was running fine before that. Now it's very slow. Hangs up during scrolling, then will continue after about 6 Secs. Hovering the mouse over a command takes about 6 Sec to recognize the cursor is there. Please tell me how to revert back to 5.6

Firefox slowed to the point where it is unusable. It also stalls, and even crashes. Other browsers work find, and my internet connection speeds are as good as I can expect.

I have uninstalled and reinstalled to no avail.

My machine is Intel QuadCore i5-3470 CPU @ 3.20GHz, 32 GB RAM, running MS Windows 10 Home on an MSI B75MA-P45 motherboard. It was assembled by Net Solution Computers of Morley, Western Australia, and has a SAMSUNG U28D590D VDU driven by an NVIDIA QUADRO K620 Video Card and RealTek High Definition Audio. I have Windows Defender and Malwarebytes as Anti-virus with Firefox and Skype running in the background.

I keep getting a red web page on firefox screaming a siren at me , flashing with writing saying "critical error"

It happens totally random and doesn't seem specific to a particular web page (and no its not while hunting down porn).

i have to run task manager, end firefox, uninstall firefox and remove every piece of firefox from my machine, run malware, remove said maleware, reboot machine, reinstall firefox.. and ""if" i am lucky and firefox doesn't open in the pages it shut down in (which considering firefox should of completely been removed from my system -- that just totally baffles me when it does reopen like that) i can continue to surf until it happens again.

the below is the only info i can get from the adware when i remove it...

Adware.Elex.ShrtCln, C:\USERS\***********\APPDATA\LOCAL\GOOGLE\CHROME\USER DATA\DEFAULT\Web Data, No Action By User, [2304], [454693],1.0.3237


I know it says chrome in it .. but there is no issues with chrome (and yes i put the *** in it) and i do not have chrome open at the time.

It happens every so often and as i said doesn't seem to be specific to any particular search or web page , it just seems to happen.

Firefox was working yesterday, however this morning when I went to launch it, it never loaded. Opened up task manager it pops open for a moment then instantly closes I have tried uninstalling it both by using windows 10 uninstall function and did a reinstall same issue. I have tried uninstalling by manually deleting both folders in program files (normal and x86). reinstall same issue. I cant run Profile Manager because it does the same thing. I went to my firewall settings there are multiple instances of Firefox ,not really sure what to do, two just say "Firefox" (no quotes) the other says Firefox "C:\Program Files\Mozilla Firefox". Any help with this issue would be appreciated.

For the past few months (it's October 2017) after starting the browser I can open 3 tabs tops before the browser slows down incredibly, things load slower, videos stop and start, ads don't close quickly. Eventually, 3 tabs or more tabs, the whole thing comes to a halt and freezes and I have to restart. I've cleared my history. Doesn't help. I don't know what to do. Thanks for any help.

Firefox did an automatic update yesterday (10/5/17). Since then, when I go to log into a site, the browser stops working. I cleared my cashe and cookies a few days ago and was revisiting/logging into sites for the first time since doing so. I tried resetting Firefox, running it in safe mode, and disabling add-ons with no improvement. I am running Windows 10. I am also legally blind and running JAWS Version 16.0.4474. At a loss of what else I can do. Thanks.
