Hello,
This is a note to let people know that Firefox 3.6 is being released today. This is an update from Firefox 3.0 to Firefox 3.6, which is somewhat of a major upgrade.
Just letting you know.

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.
