Many updates have occured since the last version :
- Now the add-on is able to download from pages which have cookie verification (like cloudflare protected pages). It can grab the cookies from the media requests and replay them when downloading.
- The request cache no longer stores data from private browsing sessions, and is no longer trying to be accessed in private browsing sessions.
- Added support for more types of MPD files that can be downloaded
- Moved the download button to be the first one on the left, for easier access on mobile devices
- Added a credits button in the bottom app bar
- Fixed an issue where some MPD files would not be detected as such because of a typo I made
- Changed the flow of error reporting. Since it's apparently not allowed to share data in an add-on compatible with Firefox 39 and earlier (at least that's what I assume) now it has become harder to send diagnostic data but at least this should make the add-on available on the store again. If you were searching for the add-on and did not find it, that's why.

Enjoy the downloads!
