670590 - Firefox 5 hangs for ~10secs with 100% CPU use when clicking on "History" menu

Status: RESOLVED INCOMPLETE

(Firefox :: Bookmarks & History, defect)

Description

[Icey]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0
Build ID: 20110615151330

Steps to reproduce:

(apologies in advance if it's not laid out correctly, never filed one of these before!) The last week or so since I upgraded to FF5, doesn't matter what page I'm on, clicking on the "History" menu will cause firefox.exe to hang with 100% CPU usage for ~10seconds, and the menu doesn't appear even after the hanging has stopped.

Started FF in safe mode with everything disabled, same problem. Followed the steps on the firefox site for hangs (http://support.mozilla.com/en-US/kb/Firefox%20hangs), still no change.

Also, when trying to clear history (Tools -> Clear Recent History), firefox.exe hangs for approximately the same time, then displays unresponsive script error (Script: resource://gre/components/nsPlacesExpiration.js:684). Letting the script continue seems to put this into a loop.


Actual results:

Clicked "history" menu, firefox.exe hangs with 100% CPU usage for ~10seconds; menu doesn't appear after hanging finishes.

Try to clear history leads to unresponsive script + firefox.exe hanging with 100% CPU usage.


Expected results:

History menu should have opened, rather than firefox hanging

Clear history should work, rather than firefox hanging until you stop the unresponsive script (or closing firefox.exe via Task Mangler)

Can you run a Places Database Integrity Check?

Paste
" Components.utils.import("resource://gre/modules/PlacesDBUtils.jsm"); PlacesDBUtils.checkAndFixDatabase(); "

into the Error Console and "Evaluate".

Watch the Output for "+ The database is sane"/"+ The database is coherent".
If it's corrupt, did you use Bookmark/History related Addons in the Past? Which?

Hey there :) Sorry about the long reply times - I'm in GMT+13, so I didn't get your update until this morning :) Here's the output of that command

It doesn't show as corrupt, but the problem still persists :( I've never used a history/bookmark addon before - always been happy with what FF gives by default :)

Thanks again in advance :)

I am apparently experiencing this issue as well... Firefox hangs for around 10-20 seconds, but in my case it does eventually open the History menu. It has persisted after clearing the history/cache, restarting the browser etc. This is on a Mac and Firefox 6.0.2. Clearing the History also results in a hang and the unresponsive script error, but the clearing does work eventually. I have had the behavior on multiple systems, Firefox Sync is enabled if that may be a contributing factor.

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:6.0.2) Gecko/20100101 Firefox/6.0.2

Looked in the Error Console and the output nearly mirrors the above; database is sane and coherent.
