438886 - Firefox 3 freezes for 30-50 seconds when first started

Status: RESOLVED DUPLICATE of bug 397993

(Toolkit :: Startup and Profile System, enhancement)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.1a1pre) Gecko/2008061203 Minefield/3.1a1pre

Firefox 3 is unresponsive for 30-50 seconds when first started.  This is accompanied by a lot of disk thrashing.  After that first lockup, it seems to run fine.  I believe this started happening after I added my Bookmarks from Firefox 2 (which does not have this problem).  Is Firefox 3 trying to preload my RSS feeds?  This has happened with every release candidate I have tired, plus the last two nightly builds, Jun-11 & Jun-12.

My hardware/software is a Thinkpad T43, 1.86GHz, 2GB memory, Windows XP SP3.

Reproducible: Always

Steps to Reproduce:
1. boot computer
2. start Firefox
3. try to do anything after Firefox starts up: click on Toolbar bookmarks, etc.
Actual Results:  
Boot computer, or if already booted, make sure you are starting Firefox 3 for the first time since booting.  This happens the first time Firefox is started after booting.  It occasionally happens after Firefox is shut down for a while and then is restarted.  However, if it is restarted right away (within a couple of minutes), there is no lockup/freeze.

Expected Results:  
Firefox is unresponsive for 30-50 seconds, i.e., nothing happens when clicking on any menu item, bookmark, etc.

Firefox should respond.

Yes, this does sound like the same bug as 397993.  Sorry my search of the bug database didn't turn up bug_397993 before I entered this one.
