Brilliant Rated 5 out of 5 stars
Brilliant... when Mozilla 'allow' it to work.
Why do add-on writers have to re-write their work every time that Mozilla do a new version. If New FF is compatible with Old FF (bookmarks etc.) how come it's not compatible with something as simple as a Spell Checker.
The 'Original English Language' should have a spell checker By Default. Aluminium is Not spelt Aluminum, Colour is Not spelt Color... and if anyone even dreams of spelling 'English' as Inglish... we'll declare war on you... And YES... I did say Spelt... not Spelled... so there...!!!***
