User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 GTB7.1 ( .NET CLR 3.5.30729; .NET4.0E)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 GTB7.1 ( .NET CLR 3.5.30729; .NET4.0E)

The sqlite thread occupies 99.94% of all included samples (see linked VS10 Profiler report in Additional Information) making the GUI (regular program use) nearly impossible.

I'm running Firefox with Firefox portable (portableapps.com/apps/internet/firefox_portable) if that makes a difference.

My addons are (all latest version):
Adblock Plus
Adobe Acrobat - Create PDF
Adobe DLM (powered by getPlus(R))
Flagfox
Google Toolbar for Firefox
Hide Menubar
Javascript Debugger
Microsoft .NET Framework Asssistant
Tab Mix Plus

Reproducible: Sometimes

Steps to Reproduce:
Altogether it has happened dozens of times. It happens fairly rarely. Once every couple of hours. It started around 3.6.10 or 3.6.11 perhaps. I can't remember, it may be before that too.

I don't remember exactly how it happens all the time. The last time it occurred as I pressed the back button.
Actual Results:  
Firefox locks up

Expected Results:  
Firefox doesn't lock up

The problem can't be reproduced. It's random and happens when you create a new tab or go back, and once in perhaps twenty or thirty times you do that.

So my hope is that my attached VS10 Profiler report can help you figure out what's wrong.

Since it occurs for me once every couple of hours, please tell me if you want any more information from debugging and I can get it for you. I know how to use the VS debugger and profiler so please ask me for more information if you think that would help.

I'll know in a day if the Firefox portable loader was part of the problem. I'm running without the portable loader now. (I didn't know about the Profile Folder setting before, that's why I used firefox portable).

I don't have a way to view the profile, so I'll have to ask for some stacks in the bug.  FWIW, this is the consumers fault; SQLite just does what it is asked.
You mean some call stacks? I'll save some if the bug occurs again. The profiler report will however show the call path that is repeated over and over.
I also agree that SQLite is probably not the problem. What I mean with SQLite-related is that the runaway calls that locks the program are to SQLite functions. I didn't investigate it further. I just saved a VS10 Profiler report and hoped that would show the source of the problem.
The bug occurred again without having FirefoxPortable.exe running or anything related to Firefox Portable, so it's a legitimate Firefox bug.

The bug occurred while I was seemingly not using the GUI at all, just reading a page. Or possibly scrolling the page.

I attached firefox.exe in VS10 and paused five times and saved the call stack. I also saved a new Profiler report. I'm hoping this will help.

I also forgot to mention the plugins I use (all latest version):
Adobe Acrobat 10.0.0.396
getPlusPlus for Adobe 16291	1.6.2.91
Google Update 1.2.183.39
Microsoft Office 2010 14.0.4730.1010
Microsoft Office 2010 14.0.4730.1010 (Office Authorization plug-in for NPAPI browsers)
Mozilla Default Plugin 1.0.0.15
Shockwave Flash	10.1.102.64
Silverlight Plug-In 4.0.50917.0

I can also list the versions of my extensions:
Adblock Plus 1.3.2
Adobe Acrobat - Create PDF 1.0
Adobe DLM (powered by getPlus(R)) 1.6.2.91
Flagfox 4.0.11
Google Toolbar for Firefox 7.1.20100830W
Hide Menubar 4.0.20101120
Javascript Debugger 0.9.88.1
Microsoft .NET Framework Asssistant 1.2.1
Tab Mix Plus 0.3.8.4

Themes:
Default 3.6.13

I'll be trying Firefox 4.0 from now on, with the same Profile Folder, to see if the bug is still present there.
Attached file New profiler report — 
it seems to show the same thing as the last profiler report. but i add it just in case. since the bug occurs so infrequently i can as well save a new profiler report.

(although, it could be generated by an add-on)
this could be related with bug 595530 or bug 556068, so navigating with the Library open on history. For sure here a view that is related to history is open and we don't left any open if they are not visible. Either there is a history view visible or a add-on has one.
I posted a new call stack and profiler report for 4.0b8. This time the bug seems to have been triggered when I opened a new tab.
