That's very interesting! Last time I benchmarked Firefox, it performed half as fast as Chrome or Gnome's WebKit. I should run my benchmarks again! I do wonder though, is this performance improvement Windows specific? It's hard to believe that Mozilla could make up the difference in only three or four months. Edit: looks like Chromium still beats Firefox on Linux: https://treeherder.mozilla.org/perfherder/graphs?highl…
Looks like it really depends on the benchmark. In some Firefox gets slaughtered, in some Firefox is the clear winner.
