Ne fonctionne pas sur firefox developer à jour

Very impressed with this add-on. Has a very high accuracy rate.
Didn't seem to work at first as I couldn't see the icon.
I had to restart Firefox with add-ons disabled and then restart again with add-ons enabled. This can easily be done from the Help sub-menu.

Worked great for a few days, then disappeared from the extensions bar in Firefox. Tried reinstalling, disabling, safe mode, and nothing gets it to appear back on there. Haven't had any issues with the Chrome version though.
