I rarely ask for help and try on my own and frequently help others, but I have a problem that I cannot solve and need your help, please.

I have tried the typical things such as restarting, starting in safe mode, refreshing, reinstalling, uninstall and delete folders and profiles then re-install, uninstall and delete folders and profiles and remove all Mozilla/FF entries in the registry then reinstall. No plugins or addons installed.

I tried disabling my anti-virus software.

I have FF version 87.0 64 bit version and even tried with an older 32 bit version. My OS is Windows 10 version 20H2 OS Build 19042.928. Both are the latest versions at the time of this post.


Regardless of what I try, my problem below persists:

When I start FF it almost starts but hangs. I can see it listed in the Task Manager. There is a little activity with Memory and CPU usage for a few seconds then no more. I cannot End Task if I try. It will hang like this for hours. Eventually I will get the home screen. If I attempt to visit a website right away it hangs (two dots blinking left & right like a school bus in the tab). If I do not try to visit a website but wait for a few more hours it will usually connect and be OK. However, if I open a new tab or Private Window I have the same problem in the new one.

Once it is up and running it appears to be working normally except for the new tabs. I have been hibernating my computer with FF open rather than shut down so that I can use it the next day. However, after a number of hours or on another day it will suddenly hang again for an unknown reason. Then I reboot and start the procedure all over.

I have tried every fix I can think of for FF. The problem may be an issue with Windows, but Microsoft has no bulletins or fixes for this one. I have updated to the latest build/version but nothing has changed. Very frustrating.

Any suggestions beyond the things I have already tried would be greatly appreciated. Thank you.

What can I do to fix the problem? Reinstalling the browser did nothing

Hi I got a problem which I think is caused by Firefox/Facebook.

Sometimes (quite often) when I'm in Facebook and scrolling down, suddenly Facebook starts to scroll on its own and then the cursor starts flickering. The only way to correct this is to restart the computer. Very often when i log in for the first time afters such a restart all my desktop icons are shown wide apart, and the I have to logoff/logon again. Then it works until the next time.

I have switched the hardware acceleration of in Firefox with the same result.

Acctually, it happend right now, and now I don't have Facebook open.

If I can't fix it i have to stop using Firefox!

I get this message; Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

I have no trouble accessing these sites with Safari. I've taken a number of steps to correct, such as running a malware scan, clear cache and history, starting in safe mode, yet nothing has worked. Any suggestions?

Thanks,
