Nice effort, but just a note; the Makefile didn't install the host application in the right place. Although I have a pure 64-bit system, the scripts only worked after I also copied them to /usr/lib/mozilla/native-messaging-hosts instead of /usr/lib64... Not sure why thou.
Also, unfortunately the script don't catch downloads triggered by a redirection or just clicking the link (yet?).
Thanks for the input. Sadly, it's not possible to completely intercept downloads triggered by clicking links using the current addon API. That's why I opted for the context-menu approach.
I'm also aware of the /usr/lib or /usr/lib64 issue, but haven't found a clean solution for it yet.
