Mozilla's rapid release schedule for its Firefox browser means there's always a new version just around the corner. To wit, almost immediately after rolling out Firefox 10 to the masses, Mozilla has made available the first build of Firefox 11 on its Beta channel. Firefox 11 makes it easier than ever to switch from Chrome, and if that's what you want to do, Mozilla's latest build will happily migrate your bookmarks, history, and cookies over from Google's browser.
The other comparatively major feature addition to Firefox 11 is a new Sync option that will synchronize your add-ons across computers. Most of the other changes have to do with cleaning up the underlying code to offer better HTML5 support, CSS text-size adjustments, and a bunch of tweaks of interest to developers.
There are a handful of known issues in Firefox 11. Scrolling in the main GMail window will be slower than usual for some users, and a handful of Synaptic touchpads will be unable to vertically scroll, Mozilla says.
