Assegnate 5 su 5 stelle

I've been using this excellent add-on for years, but after upgrading to FF44 it no longer works.

I looked for a replacement and decided to use Restart 1.2.8 because it was updated about a month ago. (https://addons.mozilla.org/en-US/firefox/addon/re-start/?src=search)

Installed and working perfectly with FF44.
