I just installed 3 from the MajorGeeks download.
It installed over 2 without a hitch.
However, many of the existing extensions/add-ons do not work with 3.
A couple that I use have already been updated to work with 3, however.
It make take a few days for the extensions to be available. I sure hope I don’t lose some of the ‘essential’ ones I use.
I love FireFox, but will wait a couple of weeks for the extensions to catch up to v3.
Only one of my PCs has Vista - I can’t load ANY of the extensions on it so I’m going to go to FF 3.0 now! ;-)
All of the extensions I use already have versions compatible with 3, but these development tree versions had to be obtained from the web sites of the authors (as of last week). In fact, add-on availability is one of the things that paced 3’s release.
