I love FF (except for this most recent release) but damn, these reports are rough.

Among Web browsers, Mozilla Firefox had the largest percentage of Web vulnerabilities, followed by Apple Safari, whose browser showed a vast increase in exploits, due to vulnerabilities reported in the Safari iPhone browser:

By and large, we found that Internet Explorer 8 performed well, and beat Firefox 3.0.7 in the majority of our time trials.
However, IE 8's performance advantage is relatively negligible. In most of our testing, IE 8's advantage was half a second or less. One notable exception, however, was in loading the English-language Wikipedia home page, where IE 8 beat out Firefox by an average of one second (IE 8 took about 2.2 seconds to load the page on average, while Firefox 3 took about 3.3 seconds). Also of note: on average, IE 8 loaded Apple's home page nearly twice as quickly as Firefox.
