ownCloud workarounds

Considering latest Google Chrome’s bugs with Tweetdeck, which I use a lot, I decided to switch back (until next time) to Mozilla Firefox. That was anyway a move I wanted to do as Google is gaining too much knowledge about me… While restoring my various logins and passwords on Firefox, I leaned about Firefox Sync, but most of all, about the ability to run my own Sync server. While there’s a good official documentation on how to achieve this, I heard that ownCloud has a plugin for that.
