I finally got around to upgrading Firefox from 0.9.x to 1.0. Very nice.
Not only does it seem faster, but all the extensions I like were available as well. Most importantly, all my AdBlock entries came over without a hitch.
I don't think I would have upgraded if AdBlock wasn't available. I can't remember the last time I had to tolerate some stupid animated flash thingy on a web site. Gah.
I only use two other extensions (tabbrowser preferences and undoclosetab), but just for grins, I installed the ForecastFox extension as well, so I have little weather icons in my status bar.
