Deactivate and delete firefox sync
At first I thought ok I must be able to get a list of all my devices that firefox is syncing to... that turned out to be wrong!
Now I'm thinking there must be a way to deactivate my sync account AND ensure that all the devices that are syncing data get their bookmarks/passwords removed as well?
Please refer to the following article, there you will get all the information to manage your Sync accounts.
How can you remove Sync from Firefox 26. It's useless and doesn't work anyway and just adds a bunch of entries in about:config. Is there a way to uninstall it? I tried the "Help" button on the sync tab but it says I "must have the current version" (I AM ON the current version) in order to use it. I basically don't WANT to use it and want the tab removed, and all the entries deleted. Xubuntu 12.04 Firefox 26 for Ubuntu canonical 1.0
