Over the last week or so, each time I use Firefox and then close it (whether I save tabs or not), the next time I go to open it, I get a box telling me it is already running and to close all instances of it, before proceeding.
In system monitor it shows Firefox.bin as sleeping and I have to end process before I can use Firefox again.
It doesn't happen with Chrome.
It isn't affecting anything, it has just become annoying that I have to remember to run system monitor to kill it, so I don't have a problem next time.
I just wonder what has happened to cause this to suddenly start happening.
I am eagerly awaiting Ultimate Edition 3.0 as I know this will all be solved with the new install. But still, it has me wondering.
