Firefox is back to being the best browser, according to Tom's Hardware. While performance is a cool thing to talk about, reliability is much more important for serious work. This is the area where Firefox really shines in the latest releases, when compared to the competition.
During the 40-tab reload, the team assessed the reliability of each browser to ensure all pages had fully rendered. The results were surprising:
Firefox loaded all pages correctly
Opera 12 required four tabs to be refreshed
IE10 required eight (and the browser crashed first time)
Opera 15 required nine refreshes
Chrome required twelve — 30% of pages were incomplete or incorrectly loaded
The Firefox gets the top place by having overall good results, not just shining in minority of areas.
