Some of us here at TidBITS were very bummed to read Steven Vaughan-Nichols's ZDNet blog post bemoaning the 10 January 2011 shutdown of Xmarks, which synchronizes bookmarks between different browsers, including Safari, Firefox, and Google Chrome, even across operating systems. We never got around to writing about Xmarks in TidBITS, but that was merely a lack of time, not a lack of enthusiasm. If only other synchronization services were as good! [Update: Since we initially linked to Steven's post, things have changed and it sounds as though Xmarks may have a second chance; see "Xmarks Is Dead. Long Live Xmarks?" on the Xmarks blog mentioned in the comments for details.] follow link
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.

Xmarks Bookmark Synchronization Service to Fold
This add-on is probably the most used/useful add-on I have on all my computers.
Urging the authour to give it a shot.
