Stopped working, keeps setting the trigger key option to [None]

Very good. Just wish hitting "more" searched the word in DuckDuckGo, or if the search engine it uses was customizable.

I just used this on Twitter and the words "Production", "Inexorably" and other words don't give me any definition :(

Overall simple and useful extension. I wish other languages were supported. Is it really that difficult to make functionality so any custom dict file can be used? It seems so funny in the year 2024 that a dictionary app is hardfixed for Spanish, German, French and English.

Edit 9 months later: The extension stopped working entirely. Uninstalling.

it does not work

inconsistent, still random 50% "no definition found" error for the past few years

Doesnt work in firefox 130.0.1. Its been a while since it was last updated. So probably abandonware!

doesnt effing work, beyond useless

It disabled the context menu, like, seriously? Oh well, I was just checking this out, I already have a good Definer add-on.

Sorry

No definition found.

Doesn't give uption to check spelling

nul

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

Language is very few and the lack of Arabic language

It used to be a great extension but it doesn't work anymore. Garbage. Don't waste your time.

Downloaded the extension and did a test run.

First word searched: "Image".

[[ NO DEFINITION FOUND ]]

Second word searched: "Approved".

[[ NO DEFINITION FOUND ]]

Wow, fascinating.

"Recommended" by Mozilla, again proving that Mozilla would recommend trash or spyware extensions randomly, quality be damned. This extension was last updated 3 years ago, there is no reason to keep it as "recommended".

A very good one, with the exception of a few disadvantages like limited vocabulary
Edit: Doesn't work anymore. Such a shame. :(
Edit2: Thank you so much for the user who recommended 'definer' by lumetrium! Even though its not as simple as this one was, it does the job.
