Firefox 8 is 20% faster than Firefox 5, matches Chrome 14

Filed under
Moz/FF

Firefox 8, which only just appeared on the Nightly channel, is already 20% faster than Firefox 5 in almost every metric: start up, session restore, first paint, JavaScript execution, and even 2D canvas and 3D WebGL rendering. The memory footprint of Firefox 7 (and thus 8) has also been drastically reduced, along with much-needed improvements to garbage collection.

According to our own benchmarks, start up, session restore, and first paint — how long it takes Firefox to appear after you click its icon, and how long it takes to re-open your previous tabs — have been continuously tackled since Firefox 7 first emerged, about two months ago. There’s a 10% difference between Firefox 5 and 7 — and a further 10% speed-up between FF7 and FF8. This isn’t merely an under-the-hood, synthetic-benchmark, on-paper thing either: the difference between FF5 and FF8 is very, very noticeable.

GNOME 3.17.2 unstable tarballs due

Hello all, Tarballs are due on 2015-05-25 before 23:59 UTC for the GNOME 3.17.2 unstable release, which will be delivered on Wednesday. Modules which were proposed for inclusion should try to follow the unstable schedule so everyone can test them. Please make sure that your tarballs will be uploaded before Monday 23:59 UTC: tarballs uploaded later than that will probably be too late to get in 3.17.2. If you are not able to make a tarball before this deadline or if you think you'll be late, please send a mail to the release team and we'll find someone to roll the tarball for you! Read more
