Anyone having strange problems with Firefox 3.0.1.1?

My work laptop (Ubuntu Intrepid) just upgraded to Firefix 3.0.1.1 this
morning, and now FF is acting very strangely.
- It doesn't come up with my home page, even though I set it and reset it
several times

- When I open up a page, only the base of the URL shows up in the location
bar, and not the rest of the URL.

- When I go to a different tab, the location bar still shows the URL (or
part of it, anyway) from the first thing I opened.

I'm just asking here if anyone else has seen this, because IRC is blocked
at work, so I can't ask people there until tonight.

Thanks.
