I’ve been a long time user of google browser synchronization. However, recently i’ve came to the conclusion (after losing my places in several ebooks ) that it doesn’t properly handle synch’ing directories. Somehow the bookmark just plain disappeared. The main convenience of synchronization of course is multiple workstations sharing the same bookmarks. When a conflict arises, google sync doesn’t seem to have any interactive resolution available. It is simply a point of management since these products really offer the same services.

It’s been 20 minutes but various tests have shown foxmarks has better conflict resolution and provides searching bookmarks from their web. Two features that I intend to use more often now.

Check out Foxmarks if you’re fed up with google browser sync
