Every time I log into sync to sync my Firefox addons, history, preferences, passwords, bookmarks, and tabs, onto another computer on Campus (the computers save my personal data on a per computer, per user basis), some of the addons are disabled after Sync is done, others are not, and it is always random on which are and which are not. This includes my Firefox theme. I have it set to sync everything including preferences. But, some preferences sometimes sync, some never sync, while only a couple of preferences always sync (like homepage). my search preferences however, never save. it always reverts back to Google. and the "where to save files" always reverts back to "downloads" which we don't have access to on student access. we have to save to drive O:. How can I fix this? I cannot reinstall Firefox on student computers or anything because I don't have access to the drive it is stored on. I do have access to my user profile folder and Firefox appdata.
