I finally managed to reproduce the bug. The cause seems to be the drop down list of the location bar in Firefox in combination with the Firebug extension.
My Ubuntu setup: Ubuntu 12.04 32-bit, all latest packages installed as of now, plus all latest firefox packages from precise-proposed as of now. Prerequisites: 1. Have a few URLs in your browser history. We need the drop down box of the location bar to be populated with some items. 2. Have the Firebug extension for Firefox installed (I have the current latest version 1.10.2) Steps to reproduce: 1. Start Firefox. On my setup it starts with one tab showing a blank empty page. No need to open any web page. 2. Go into the location bar of Firefox and press ALT-DOWN. The drop down box of the location bar opens. No need to select anything there. 3. Press ALT to open the HUD and enter a search term which creates some results in the HUD. 4. Press ESC two times in the HUD to make it disappear, 5. Go into the location bar of Firefox again and press ALT-DOWN again. The drop down box of the location bar opens again. No need to select anything there. 6. Press ALT to open the HUD again and enter a search term which creates some results in the HUD. 7. Crash! This reproduces the bug more than 95% of the time. In some rare case I need three or four rounds of openening the location bar and the HUD, and sometimes additionally going up and down the items in the drop down box of the location bar with the arrow keys to get the crash. If I disable Firebug everything works fine and I'm not able to reproduce the bug then. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1025011 Title: HUD search causes firefox to crash Status in The Mozilla Firefox Browser: Confirmed Status in Unity global menubar extension for Firefox and Thunderbird: Fix Committed Status in “firefox” package in Ubuntu: Fix Released Status in “firefox” source package in Natty: Fix Committed Status in “firefox” source package in Oneiric: Fix Committed Status in “firefox” source package in Precise: Fix Committed Status in “firefox” source package in Quantal: Fix Released Bug description: Searching for any text causes Firefox 13.0.1 to crash on Ubuntu 12.04 ( both 32 & 64 bit **1).
