I, along with millions of other people, am a fan of Xmarks. But today's Xmarks blog post by Todd stated that this wonderful tool will be shutting down. They just weren't able to make a profitable model out of it. The new Firefox Sync definitely doesn't help matters. While I'm a big fan of Xmarks, I consider baking Sync into Firefox to be bloat.
I first started using Foxmarks to synchronize my bookmarks across my home and work computers. As time went on, I found a few other aspects very useful and unfortunately Sync lacks them. The first item is the ability to separate my bookmarks into groups. At work I'll bookmark intranet sites, but I can't use them at home. At home I have bookmarks that I'll never visit while I'm at work.
The next feature was syncing between IE and Firefox. While I use IE Tab Plus to embed IE into my Firefox, sometimes I need to actually open IE. Xmarks has it so that the very same bookmarks are there.
My current mobile phone is just a phone. When I travel, I like to have the ability to log onto Xmarks and have access to my bookmarks from any computer.
I think the name Firefox Sync was poorly chosen. It is a very limiting name and has the connotation that it will never work with anything other than Firefox.
The Xmarks team was clearly able to overcome these items, so I hope that Mozilla will as well. My 30 seconds of searching didn't bring me to a list of enhancement requests in Bugzilla for either Firefox Sync (or Weave), but I'm sure someone will read this and quickly let me know where to go.
