I recently upgraded my VZW Note 3 from 4.4.2 to 4.4.4. I did a return to factory reset after the install so everything started fresh. I installed FF34 and enabled Sync. I am now experiencing two, probably-related, symptoms of bugs in FF. 1. There is no "Desktop Bookmarks" option on the Bookmarks tab 2. There is no response to a press of the Menu button on the RecentTabs/History/TopSites/Bookmarks/ReadingList tabs Points to note: 1. Immediately after a fresh install of FF34, and prior to signing in to Sync, the Menu button works normally on the RecentTabs/../ReadingList tabs. Only after logging into Sync does the symptom appear. 2. Sync is properly enabled with checkmarks on all options in >Settings>Account>Firefox, and History and Passwords appear to be syncing properly 3. The symptoms exist with or without AdblockPlus installed 4. In all other respects FF is functioning normally I have: Uninstalled, rebooted, and reinstalled FF twice and the symptoms are fully reproducible.
