Hangs for 30 seconds on launch
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b4) Gecko/20090423 Firefox/3.5b4 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b4) Gecko/20090423 Firefox/3.5b4 Every time I launch 3.5 Beta 4 the browser will hang for 30 to 40 seconds. Reproducible: Always Steps to Reproduce: 1. I install 3.5 Beta 4 2. Open Firefox.exe 3. Browser does not appear for 30 to 40 seconds before appearing. Actual Results: Browser hangs and window does not appear for 30 to 40 seconds. Expected Results: Browser window should launch immediately or within a few seconds. This also happens on the latest nightly builds. I have uninstalled/reinstalled, deleted every trace of Firefox every being on my system, started in Safe Mode, tried opening with a different profile, removed all the extensions/plug-ins. Opening a subsequent window has no issue at all. Using 3.1 Beta 3 or earlier also has no issue. I can have both 3.0.10 installed and 3.5 Beta 4 installed alongside each other, and the 3.0.10 build opens perfectly fine every time. CPU will go to approx. 50 for the 30 to 40 seconds it takes to load. I have installed this Beta on other machines and have no issues.
Is this with default set of bookmarks and no history?
Version: unspecified → 3.5 Branch
(In reply to comment #1) > Is this with default set of bookmarks and no history? Yes. I have tried a completely fresh install with default bookmarks and no history as well as trying with an existing profile which has bookmarks/history.
When I start Firefox 3.5 on a really slow Windows XP computer with a new profile, it takes 13 seconds the first time, and every subsequent restart 3 or 4 seconds. With my default profile however with a bunch of extensions and 6 months of history, it takes 1 minute and 10 seconds on the same computer.
Tried with Firefox 3.5 RC1 today after uninstalling 3.0.11. Still the same problem, possibly worse than before. I have tried installing on the same computer with Windows 7 installed instead of Windows Vista (dual boot setup) and all versions of 3.5 load quickly.
I saw this on a friends XP system as well. Is there a easy way to debug what's going on during launch?

timeless may have an idea.
https://deloper.mozilla.org/en/How_to_get_a_stacktrace_with_WinDbg you have three choices: 1. use !analyze -v -hang w/ windbg when it's starting up 2. use adplus (it comes with windbg, you'll need the same symbols as described in the dev-mo article, but you'll also need to read some documentation) 3. use process explorer (you'll need the same symbols as described in the dev-mo article, you can ask it for a stack trace fairly easily, but again, i don't have a tutorial). whichever you do, we'd only ever want stack traces as attachments, no pictures, just text, no binaries, just text, just stack traces, and only as attachments, not comments.
I have tried to follow Timeless' instructions about providing a stack trace - if I've done something wrong, let me know and I'll try again. This is all new to me :)
Duplicate of bug 501605.

It's a real shame that this bug didn't get spotted earlier :-(
