CCleaner always asking to close FireFox

CCleaner for Windows CCleaner Windows Bug Reporting
1

Same problem here. I was about to make a new post about it.

I am getting the false positive error that FF is open and asking my permission to close before [manual] cleaning. FF including other Mozilla service are not running as I have verified within TaskManager and Process Hacker.

I have everything on manual, no updater, no smartcleaning. I use Custom Clean.

Also, the last time FF was updated for me was on April 2. The issue happened moments ago.

This isn't a major problem, just a minor annoyance which started happening a few CCC versions ago. I'm using W10.

I have split this out to it's own thread, it is not the same issue as where it was originally posted. 

That was related to Smart Cleaning which you say that you are not using.

First of all are you giving Firefox time to fully close before running CCleaner? 

It can sometimes take a while for Firefox to fully close. (And it may not be showing in Task Manager because it is in the process of closing).

However what you describe sounds more like a known Firefox bug where it doesn't close properly. 

It's something that has been happening for years and it usually starts happening following a Firefox update.


(Best guess is that the update hasn't installed correctly for some reason?)

There are many other such threads - generally if/when it starts happening for you then the way to fix it is to reset Firefox or sometimes you need to uninstall/reinstall Firefox.

Thanks for moving to it's own thread and providing links to a few other previous threads.

This issue is something very new, within the last few months that's been happening.

I reviewed the above links and they seem to be from around 2016- 2019. Interestingly, they seem to have a commonality: Windows 10.

A few months ago, I performed a fresh and new Windows installation, back to Windows 10 from Windows 11. I didn't experience this with Windows 11 which I stayed with more than 2 years.

As I mentioned, when it does happen it's quite random and the interval is the same as before in terms of giving Firefox time to close completely.

Anyway, this is more of minor annoyance than anything. I'm not going to uninstall/reinstall Firefox because unlike Chrome, it doesn't restore all your settings including themes like Chrome synch does. I now think this might be related to Windows 10 too.

Personall I think it's Firefox updates, but it could equally be Windows updates. 

They do tend to happen about the same time each month, and both are know to introduce various bugs at times.

I understand about not wanting to go through the hassle of a reinstall.

PS. You do know that you can sync Firefox too?

I mentioned FF synching above, it doesn't synch your themes and layout but does keep the tweaks ?
