There's nothing terribly exciting to speak of in today's Firefox 3.5.5 update; from the looks of the tiny changelog, it looks like one critical security fix and a few other minor bug fixes will make their way to your browser. Mozilla should officially announce the update to Firefox 3.5.5 sometime later today—they're currently hard at work pushing the Firefox 3.5.5 update to their servers. Once they've got their ducks in a row, you can download the update directly from Mozilla here; in the meantime, you can grab the downloads straight from FileForum for Windows, Mac OS X, or Linux. If you're in no rush to update manually, Firefox should prompt you for an update in the next day or two. [via gHacks]
