it doesn't have a large dictionary, and that's the only complain.

These type of extensions I consider essential and this one, does the job.

Works great!

excellent

Love this add-on. For anybody reading this that has issues, one thing I have found is that

THIS ADD-ON STOPS WORKING WHEN YOU'RE ON A VPN.

So if you have disabled/enabled, removed/downloaded, changed settings, etc. trying to figure out why it isn't working, that is one possibility. I can't verify if this is true for all VPN services, just some.

I do love this addon, though I wish it had more options, like to check something I wrote myself it it means the same I think or even make it show it's own search bar on addon icon click as I believe it is more convenient then getting new tab and googling it.
Still, can't recommend it enough

This was a decent Dictionary but just quit working. Not as much info like the others unless you went off page.

It has stopped working since yesterday, the last straw for me to ditch Firefox I guess

sorry guys, does not work at all, double-clicking nothing happens, trigger key, nothing happens

i wish if you support arabic as well

Language is very few and the lack of Arabic language

It was just updated this morning, maybe there's a new bug, but it did not work until I added a trigger key.
