Not really an update or patch, 3.5.1 installs like a reinstallation or fresh install of the browser. Midway though install on an XP machine with Firefox 3.5, the following error message popped up: "Incompatible Add-On: Microsoft .Net Framework Assistant 1.0." The install gives the option to check for a compatible version (which was not found).
The installation continued, however. After the install, Firefox redirects to a page indicating that the user has just installed the latest (and safest) version of Firefox.
A noticeable improvement right away was how quicker version 3.5.1 opens than 3.5 on the same machine. Multitabbed browsing also seems a bit speedier.
Some add-ons were updated. All survived the update intact and there were no issues with the following add-ons: FoxTab, Greasemonkey, Interclue and Twitterfox.
In version 3.5, we had noticed a few crashes viewing video on various sites. It seems that problem has been fixed in the update.
Kudos to Mozilla developers for the quick turnaround time with this update. Fixing a major security flaw and improving the performance and response time of the browser running on Windows is no small feat, especially considering it was developed in less than 72 hours.
