Firefox 18.104.22.168 vs. Firefox 3 Beta 3
I have been running both and doing some comparisons, especially for speed. On my machine and with my ISP I'm finding that Firefox 3 Beta 3 is faster at everything I've tried and compared.
Most pages on Long Range Hunting load in 3/4 to 1/2 the time they do with 22.214.171.124. I don't even use IE anymore because of having to wait compared to FF.
The only drawback, for now, is that most Addons/extensions don't work but I'm finding several that do.
