The new Firefox/Deer Park Beta 1 is out and the things changed even since Alpha2 (which I’ve been running on all my computers for a couple of weeks now) is pretty outstanding. Item number one has long been my number one beef with the Mozilla family of products:
Automated update to streamline product upgrades. Notification of an update is more prominent, and updates to Firefox may now be half a megabyte or smaller. Updating extensions has also improved.
I’ve only experienced maybe one or two crashes in the two weeks or so I’ve been running it. So, if you feel just a little risqué, you can head over to the Firefox Project Page at mozilla.org to access the downloads and release notes.
