Google has officially released their popular photo management application Picasa for Macs, after years of offering Picasa as a free Windows download. It's an exciting announcement for anyone who's looking for a good photo management app on OS X that isn't iPhoto or for anyone who's used and fallen in love with Picasa on Windows or Linux. This release still sports the beta tag, so you can expect a bug here or there, but overall it appears to boast most of the same features as its counterparts. That includes:

Firefox only (Windows/Mac/Linux): The Tabhunter Firefox extension adds quick keyboard-based tab switching to Firefox—sort of like Launchy for Firefox tabs. Just invoke Tabhunter, start typing, and Tabhunter searches for a match through all your tabs.

iPhone/iPod touch only: If recession budgeting meant choosing an iPhone/iPod touch over a Kindle when the dust cleared this holiday season, you're in luck: Stanza is a free and fantastic ebook reader for your iPhone.

Firefox with Greasemonkey: The Gmail Unread Message Count in Favicon Greasemonkey user script displays your unread message count on the Gmail site favicon.
