Sorry, don't agree. Firefox has adblock and adblock is the only way to read the web without all those annoying crapverts. Plus the million other addins that make browsing on Firefox so pleasant (e.g. mouse gestures).
Glad to see Safari on Windows. At last we can see an end to the incessant chant from the Windows web development Muppets of "I can't test it on Safari as I don't have a Mac". Not that those ********s would even test it on Firefox.
Still, it's nice to see another competitor for IE.
I hear you, adblock and double click on tab bar to open new tabs are the only two things that are keeping me using firefox over safari at the moment.
