It seems that Mozilla has gone ahead and released a release candidate to beta users for Firefox 3.5 despite any prior announcement.

Some features found in the update (which Mozilla says totals 5,000) include build-in video, a private browsing mode, geolocation to provide certain websites with the user’s location and finally the faster loading of pages including JavaScript programs.

Those brave souls who want to dive head first into the update before its officially released later this month can grab the release candidate here.
