It's terrible. It doesn't provide results for nearly every single lookup. I'd say it's a bust!

its great. had it for a few years on a different computer.

UPDATE: Apparently, this doesn't work well with VPNs. Five stars anyway since it's a great tool or everyone else. Would appreciate a workaround or VPNs though.

Consistently get "Sorry No definition found" for basic words like "basic", "words", and "Enjoy." I added this add-on because of the great reviews but I'm not seeing? What am I doing wrong?

the French dictionary is very incomplete. This makes this extension completely useless at least for this language

good

Amazing extension to use when reading novels!

amazing!

Awesome the one out of five times it works, but even having nailed all the about:config variables, it still sometimes is useless and no definition even appears.

If I could use this with selected words. sometimes I struggle to understand idioms.

2025 Review: Does not know *any* words.
Any (adj): None at all.

2021 Review: Pretty disappointed. I wanted a dictionary for words I don't know, however the dictionary is apparently fairly basic. It *does* work, it just doesn't contain multiple uncommon words I tried.

Thanks

Just as a notice for anyone who has issues making this extension work:
Using a VPN like Surfshark or NordVPN on your OS/Browser will prevent this extension from properly working if you enable certain settings; in the case of Surfshark, it's the NoBorders settings I believe. This can also be triggered in extreme cases of Adblocking on the OS level by softwares like Adguard if the settings are too strict. You're welcome!
