  1. I dont think they have released final version. About Mozilla Firefox shows version 4 eventhough if you install RC1 or RC2 manually.

  2. File size for 4.0-RC2 & 4.0 is exactly same. Once I install it takes me to http://www.mozilla.com/en-US/firefox/4.0/whatsnew/ page which is RC page. Its still confusing whether they are going to release RC2 as final version as there are no fixes after RC2 ?
