I'm a little conflicted about the Firefox Sync feature. On the one hand: yay! On the other... it's a lot more difficult to set up sync in Firefox than in Chrome. I got to work today and was dismayed to discover that I couldn't simply login to Mozilla's server and sync up my bookmarks from home, but that I needed the sync key from my computer at home to get this working. Boo. That, or you need to have the devices you want to sync in the same place and use a Netflix-like "Add Device" feature.
I get it. Encrypting locally is more secure, but they've made this system SO secure that it's actually irritating. I wish I at least had the option of foregoing this sync key business.
Anyway, now I know to put my sync key on Dropbox so this doesn't happen again.
