Source? Rated 4 out of 5 stars
The addon appears to work well in the replacement of this much needed and deleted funcionality.
On other note, aren't you obligated by the license of your own choosing (mpl) to release the source code with the respective addon? That would be much appreciated.
Thanks for doing that.
I just unlocked the source. You may find it here: https://addons.mozilla.org/firefox/files/browse/98067/
