When I quit my browser, I get a long hang (~25s) in shutdown while Firefox does some work. Here is a shark profile for that hang.

I see something like this (20+ second hangs on shutdown) all the time with my testing profile, especially if anything else disk or CPU intensive is going on in parallel.  Profiles suggest disk i/o and ExpireHistoryParanoid.

Anything I can provide here that would help with debugging this?

This bug is filed against the places branch builds, specifically, and won't block Firefox 3.6.

It seems like bug 407981 is simliar/related for release builds?

Bug 407981 isn't what I'm seeing.  I guess I'll file.

I think you are seeing the same bug.  It's all caused by expiration on shutdown (which we've had since Firefox 3.0).

One difference is that my window is still there, but I guess if we're expiring sync off my Cmd-Q it might be a similar issue...

are you still seeing this now that async expiration is landed? please close if not.

Reopen if you can reproduce in Firefox 4 and mail us a database to test.
