I recently had to redo my Firefox installation on one of my computers and I noticed that the Sync button is missing now from the Customize screen so that I can no longer add it to one of my toolbars. Like many users I don't sync my tabs but rather I use Sync to sync my bookmarks (and a few other things) across my devices, as such the new 'Synced Tabs' thing doesn't really do me much good (also because I use Classic Theme Restorer to make Firefox look like one of the much older versions of Firefox from before you tried to copy Chrome's interface, If I need more screen space I actually do know where and how to press F12 to go fullscreen), as was pointed out on the actual Firefox Synced Tabs Wiki page "At best, synced tabs will provide benefit to some users, some of the time. ", so why the heck was the button removed???? Many of your recent decisions have really left me wondering if the developers really take into account how other people use Firefox or not when they make changes (clearly they don't in my personal opinion), instead it seems they just want to make it work the way THEY want only. I find it really annoying that there's also no feedback generated anymore when I click "Sync Now" in the Tools menu to indicate if Sync was successful or not, wth?
