We have updated firefox on a few of our machines for testing and it worked 
fine for me...

But one of our users has reported a problem with a particular extension 
which seems odd - the extension works the first time that 3.6.4 uses it 
but not after that.

To test this I've installed the extension myself - it does the firefox 
restart and all seems well; then quit from firefox and start it again and 
we see a segv.

More puzzlingly is that if we remove the extensions.ini from the profile 
then firefox will work again (with the extension still enabled), but just 
that one time.

Just in case this is something weird about our setup here can someone else 
test this please?

1. update to firefox 3.6.4
2. Go to https://addons.mozilla.org/en-US/firefox/addon/421/ and install 
the "MR Tech toolkit", this does a restart.
3. Quit firefox
4. start firefox again

For me that crashes, but if I delete:

   ~/.mozilla/firefox/<profile-dir>/extensions.ini

then the next startup will also work.

I get the same behaviour on sl53 and sl55 machines both i386 and x86_64 
but we are running the i386 firefox on both.

I had just about convinced myself that this is a problem just with this 
extension but another user has reported a similar effect with the 
"Delicious bookmarks" extension.

The original user has told us that he doesn't have the same problem with 
the "MR Tech toolkit" extension using firefox 3.6.4 on Ubuntu 9.10 so I 
don't know if this is a problem with our environment or the TUV srpm.

Any results (either positive or negative) would be useful to narrow down 
where the problem is.

At the moment I'm looking at hacking our wrapper to remove the 
extensions.ini file very time firefox is launched, but that seems like a 
really really evil hack.
