Mozilla made available the beta version 23 for Firefox browser a couple of days ago, but today they started to push it to the users through the automatic update mechanism and also posted the official release notes.
At a first glance, the most visible changes are the stub installer (securely downloads the resources that need to be installed), which has been available in the previous release and the updated Firefox logo.
Only two of the new features introduced in Aurora made it into the beta, one of them being Mixed Content Blocker turned on by default, a move designed to protect users from man-in-the-middle attacks and eavesdroppers on HTTPS pages with HTTP resources.
Additional modifications include support for new scrollbar style in Mac OS X 10.7 and above, improved interface for “about:memory,” a simpler UI for notification of plugin installation and the possibility to change the search provider in the entire browser, not just the search box.

According to our sources, Mozilla plans to intensify the development of the beta release and launch more builds.
The average number of revisions released until now is six (about one per week), but with Firefox 23 there will be more releases per cycle, between the first and last week of development.
Next week there should be two releases available on their servers, which will be pushed to the users when ready.
