I have been seeing the same in Vista HP, taking 15-20 secs or more to fully close.  I update every day, sometimes more often to hourly's.  

I use minimal extensions and have been using them for months now, so doubt its an extension issue.

I am seeing the same issue with 3.0 beta 1.  it never happens on 2.0.0.11.

Every time I exit the program it takes 5-10 seconds before I can restart it and the CPU goes to 100% or close to it.




this is the info on my build of firefox:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b1) Gecko/2007110904 Firefox/3.0b1

An update on this - I just tried it in Firefox safe mode and the same thing happened.

That has been talked about several times before - it's mainly the "expiration" (cleanup) code that runs in the Places database. There are several bugs with improvements, some of them already finished (like bug 407124, just checked in today), others still being worked on.

problem gone now that  bug 407124 is fixed?

Comment 6

I think it is not fixed. 
A process is left during 10～15seconds after shutting down Firefox.

Meanwhile, no message such as "During shut down, Please wait for a while." is shown on a screen.

This bug(100%cpu) was solved with latest/current FF.

However, there is Bug 407981.
