I waited for a couple of minutes, and nothing changes, so I have to kill Firefox. Reproducible: Always Steps to Reproduce: 1. Open preferences dialog through menu 2. Click Applications tab. Actual Results: Firefox freezes. Please note that create a new profile DOESN'T make the problem disappear. Also, this only happens on my MacBook Pro (Mac OS X 10.6). Can't reproduce on another Windows 7 machine.
This problem is still reproducible on beta 8.
Still reproducible on beta 9.

This also happens on latest Minefield downloaded one hour ago.
jmlane on irc reported that this problem doesn't affect his/her 10.5.8 (32-bit). So this might be 64-bit specific. The affected machine of my friend is also running 10.6.6 (64-bit).
Just found out that, this won't happen when Minefield is run in 32-bit mode. So it is 64-bit related.
Summary: Freezes when application tab in preferences dialog is pressed → Clicking "Application" tab in preferences hangs in 64-bit mode
After some tweak and help from juanb and ashughes from IRC, I may have found the cause: After removing the realplayer plugin from /Library/Internet Plug-Ins, and remove the program that handles local real format files (mplayerx in my case), Minefield in 64-bit doesn't hang any more. Reinstalling the local program (mplayerx) again also doesn't cause hanging any more. One thing to note here: merely remove the realplayer plugin doesn't fix the problem. It stops hanging after removing or reinstalling the local program than handles real formats. So it is hard to tell which actually causes the problem, especially now the symptom can't be reproduced for the moment. HTH.

I guess it's ok to mar this wfm now
