Please make BBlog Firefox multiprocess compatible! :)

I've migrated it already a few months ago but i have not published it because it was not in firefox stable.
Now we have ff 50 and web extensions are stable right now.
I will push out a web extension version soon but this means you have to install it manually because it cannot be done by the auto-updater. Settings cannot be automatically transfered.

Web Extensions are fully multiprocess compatible.
