Using ff52 esr with xp. After closing ff, I check with task manager, (and "what's running"), and they show ff is closed, yet when I try to restart it, nothing. If I restart computer, ff starts fine.

Update: Turned out that 'Malwarebytes Anti-exploit' was the problem, not an add-on. Disabled it and the problem went away. Also seems like FF is running faster now too.

Hi,

Assuming that you close Firefox by clicking the 'closing X' - would you do it like this :

3-bar menu => at the bottom : Exit = power button.

Does that make a difference  ?

Did you look under the Processes tab in the Windows Task Manager?

That's what I thought the OP meant in his original post .....

Thanks Happy & cor-el. I disabled a couple of add-ons, and FF closed fine. If it acts up again I will try using the power button Happy mentioned. Recently updated to FF-52, so that might have conflicted with an add-on. Thanks again guys.
