[PLUG] Firefox crashes with lots of tabs open

I'm running Kubuntu 8.04 (avoiding KDE4 for now).  I find when I have a lot of tabs open in Firefox it's very likely to crash.  The backtrace below was from a session that had 3 windows and 60 tabs open.  Couldn't figure out what the cause was, so I started it from a terminal to catch the debugging info.

There are several dozen lines like this:
(firefox:31173): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJEC
T (object)' failed

Then this:

The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadIDChoice (invalid resource ID chosen for this connection)'.
  (Details: serial 21390346 error_code 14 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Locking assertion failure.  Backtrace:

Segmentation fault
Any ideas on what might be causing this?  Should I try creating a new FF profile?  Should I submit a bug yet?  I've tried googling this but can't find anything that seems relevant.

I'm using these extensions:
Ad-block Plus
All-in-one Gestures
Cookie button
Forecastbar Enhanced
keyconfig (because I always hit Ctrl+Q when I mean to hit Ctrl+W)
Nuke Anything Enhanced
Tab Mix Plus
