Funny you should say that...I figured after hearing about it from several sources, I'd give it a shot.
I imported my preferences/bookmarks, etc from Navigator, and it worked fine, except Flash wasn't compatible with my version (?) and it messed up how videos would play using Windows Media Player, so I deleted it.
After reinstalling WMP, everything is back to normal--to whatever degree normal was before I installed Firefox.
Is Flash compatible with Firefox at all, or did I have the wrong version of something.
As a browser, I liked Firefox fine....
