I literally just started using this extension and thought I was in heaven; bookmarks across ALL of my browsers?!? And why did I not use this before?
Well, anyway, I had to find something similar and I think I have. I’m using Google Sync and Firefox Sync. Now, they don’t cross-sync, but I can import bookmarks from Chromium to Firefox and sync from there (since Chromium is my main browser on Ubuntu and Chrome is on Windows).
I tried to give LastPass a shot, but it didn’t really work for me. Granted, it was cross-browser and platform, but I’ve had difficulty setting it up. Anyway, I’m going to go with this Google Sync and Firefox Sync option. It’s not ideal, but better than nothing, right? I’ve outgrown Delicious bookmarks, because tags aren’t cutting it. Searching is a hassle, organization is a hassle, and it just doesn’t work for me right now. I might wipe everything out of my delicious account and restart and reassign tags (OMG, that will take so long) but I’m not sure.
We’ll see if a new Xmarks-like service starts up in the future. If so, I’ll be trying it out, for sure.
