This bug isn't as trivial as you might expect! I wanted to comment on the
extension that allows Firefox 1.01 to spoof IE  and Opera, etc. IT CAUSES A JAVA
ERROR THAT STUFFS FIREFOX.
The only way to resolve it is to lose *all* your preferences and extensions. To
me, that's pretty serious. But can I comment on this extension? No, I can't.
Hence this bug needs fixing - pronto.

Reproducible: Always

Steps to Reproduce:
1.Use "User Agent Switcher 0.6.1"
2.Close Firefox
3.Try to start Firefox again.

Actual Results:  
Error message about not using Netscape java in IE, use IE java instead. Firefox
simply will not load after this. (THIS IS SERIOUS) There are several pages on
this error...google for "JAVA error opening Firefox" and you will see that you
are not alone.
I tried to comment on this extension on the download page, but I just can't, so
presumable other users are still downloading this extension, unaware that it
will break Firefox.

Expected Results:  
Allowed me to comment on the extension and warn others not to download it!

This extension worked fine with earlier Firefox versions, so one assumes it will
work with V1.01. Instead, it totally stuffs Firefox. I had to resort to IE to
get this error fixed. Not good.
