I have had nothing but problems with your new Sync setup. There are other issues as well. (1) I was not given the option to "unlink" my old sync in my desktop Firefox. I followed all the instructions and it simply wasn't there. (2) When I disconnect from Sync, it loses all my sync preferences, including even the Device Name. (3) After deleting the old sync and setting the new account up on my mobile device, I found that there does not appear to be any option to disable Sync on my mobile device. THAT IS A BAD THING. I HAVE NO USE FOR AN "ALWAYS ON" SYNC. I WANT TO SYNC MANUALLY, AT MY OWN DISCRETION. (4) There is no feedback showing that either my desktop or mobile device are syncing. This is an egregious oversight. I don't know when I can TURN OFF my sync, because, as I mentioned already, I HAVE NO USE FOR SYNC THAT IS ALWAYS ON. There must be an option to turn it off (which means feedback telling me WHEN I can turn it off), or I will simply do without... which means your new sync is now WORSE than the old one. (5) The sync settings on my mobile device are grayed out and not available for interaction... and they are the same WRONG, default settings my desktop keeps returning to. (6) This is really terrible. I would have been better off staying with Firefox 28. Fix this. =========== In addition to those primary issues, I would also like you to know: (7) I do not care to be forced to have my refresh button inside the address box. I liked it where I had it before: OUTSIDE the box, next to my back and forward buttons, where it properly belongs. Stop trying to Chrome-ify Firefox. That's just dumb. (8) While I appreciated the fact that you are trying to save space, having the forward button only appear when it is "necessary" means your interface is moving around, which is generally A Bad Idea. (9) I object to the removal of the "add-on bar". I used it for holding add-on controls that I do not care to be putting on my upper toolbar. And since there is... (10) ... no longer any apparent way to add a new toolbar, getting rid of the add-on bar means I now have to put space-consuming add-on controls on my main toolbar, which defeats your entire intent to save space there. All in all, firefox, I have to say that your "new" version 29 was badly done. Change for the sake of change is not a good thing. In order for change to be a good thing, it has to be BETTER than the old version. This is way worse. Not JUST because I liked it the other way, but because you screwed up a bunch of things that used to work fine. It has to be better for the user, that is. Not just better for your developers. As a very long-time user of Firefox: this release really let me down.
