Does not work with firefox 57.0

Asendamatu ja kõik toimib kenasti juba aastaid.

Useful, but why disable it on current versions of Firefox?

Why is it full of typos? It underlines the correct word as an error and suggest misspelling with common typos. Somebody has accepted all corrections? I can't trust it if it's faulty.

Have been using this dictionary for ages. Very helpful, especially for a non-native speaker like myself.

I have been using this for a year or so, Easy to use, works nice, no complains.

Thanx for this great addon ^_^

This is a very helpful add-on for people with mother tongue other than Estonian.
