[Jim Jeffery not reading bug-mail 1/2/11]

Tested using the latest hourly which contains the huge DBLI patch.
https://hg.mozilla.org/mozilla-central/rev/4c2ddc60f360 
Running Win7 x64 

STR: 
1. Open https://tbpl.mozilla.org
2. Click on any cset listed on left side of page
3. Click 'back' or use back button mouse... - Crash!

Will try to repo with a Nighly build so we can get a crash + symbols, hourly's don't have symbols.

Doesn't happen for me in my own debug build of changeset 37776fc33437. Opt-only maybe?

Crashes in Safe-mode, also crashes when opening the attachment in this bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=770000

then clicking back to return to the bug.  the attachment is a short flash video.

Also just now tried clearing cache, - still crashes.  Does not seem to crash in a quick test on a new profile.  This could be fun trying to figure out what in my profile is goofy if that's the case.

Using http://hg.mozilla.org/mozilla-central/rev/d9d61d199b11 no Crash for the PGO and non-PGO Tinderbox Build over here. Also tried Safe-Mode.

Well, being the impatient type I 'reset Firefox' before the Nightly came out, re-installed my 3 addons, and tweaked a few pref's that I always change, and so far.. no crashes.  Guess this is good, but now it will remain a mystery as to what was causing the crashes. 

I'll be glad to file a bug for an enhancement, but is it feasible to have Firefox dump the pref's that are reset after using the 'reset Firefox button' ?

Closing this for now as WFM, reopen if this starts up again.

This is being tracked in bug 770041 now.
