Ccleaner gives message of "Firefox needs to be closed. i though it was Ccleaner that was the problem. it's not Ccleaner's problem... I get the same message when I run advanced system care... when I click 'close for me' it just skips it over and over. i then run it after starting PC and it still tells me FF is running. the 1st time it lasted for weeks(summer-ish of 2023) and seemed to fix itself. and it also wasn't fixed with 1 or 2 FF updates because i was waiting to see after updates that it would be fixed but wasn't. And I can't find Firefox running in Windows or advanced system care task manager. which means i cant close it manually. so I'm pretty sure it's a Firefox system problem... somehow FF is still running hidden in the background. i run malware fighter and anti virus to see if something is using it but comes up empty.

peculiar, Ccleaner did an update the day after writing the above comment and is actually shut down FF when it asked... and again doesn't ask anymore on next cleanings. so the problem IS with FF.

Interesting... I wound open Task Manager, run Firefox in Safe Mode, then close Firefox and see if it's still running.

CCleaner might be getting confused with background processes like the Mozilla Maintenance Service (maintenanceservice.exe) or the Default Browser Agent (default-browser-agent.exe).
