Review for WebDAV for Filelink by AegisGFX
Rated 3 out of 5 stars
Actually works fine with OwnCloud if you follow these instructions;

But will not use the Thunderbird password manager on Windows (Works fine on Linux, the developer obviously uses Linux like me) so you have to put the username/password in every time you start Thunderbird. Confirmed its not remembering password for XP or Mac either, so this is a definite bug.
Fix that bug and it will be a perfect addon.
