Firefox creates almost 200 processes on exit, 100% CPU
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.

In summary, the problem in Firefox 112 appears to be caused specifically by "Allow for Session" cookie permissions because Firefox is running a background task to remove site data (offline storage folders) for those sites at shutdown.
The thing with site data is that there is only one folder named "to-be-removed" and Firefox removes it for the first Allow for Session permission. Doing that again for every additional Allow for Session permissions is wasteful, and those attempts seem to be failing very slowly so the wasted processes take a long time to clear.
Firefox 113 fixed that, although it might have been a Band-Aid fix that will get revised in the future when related bugs are worked on.

Alright, thank you jscher2000. I will wait for the next release and see if its fixed :)
Hey everyone! ...well, this seems like good news. We'll see when 113 is released. I definitely have "allow for session" cookies and it sure seems that with the processing power of Windows and Firefox that it should take... no more than a blink of an eye?... to delete these cookies from one Firefox session. But then I've had allow for session cookies for quite some time and never had an issue until 112. Any idea what changed that caused the issue? Just curious... Thanks, everyone!
...I can confirm that update 113 fixed the "spawning excessive processes on exit" issue. Firefox now exits cleanly and quickly without spawning ANY additional processes!
Thank you!!
