We upgraded to Firefox 4.0

We finaly decided to upgrade after reading more tests and news about the Firefox 4.0.
Many Addons are working with the new one as well,unfortunately not Blackout.
The personas still can be used,haven't known that before.The browser is launching within the blink of an eye,amazing!
The new one can't be installed seperately and is while the installation replacing the older version on it's own.But we deinstalled the privious version anyway.
The new browser is while surfing much faster as the privious Firefox 3.6.16.
We can recommend to upgrade,no problems occured while the process.All bookmarkes got recognized and so on.
We backuped the privious version with the free tool "Mozilla Backup" and could transfer back,but after the first tries-never!
Firefox 4.0-the best browser of all the new ones we tried.
