It functions as intended, but it is missing the definitions of so many 'higher-level' English words that it's almost useless for me. For example, no definition found for a word like "serendipitous" - what's the point if this extension can't define the higher-level vocabulary that I actually need defined?

90% of the time this extension finds no definition for the words unfortunately

This extension just doesn’t know a lot of words. Words like superlative, a word common enough for me to recognise it but obviously obscure enough to not know already. It's a dictionary and it literally doesn't even know like 30% of the words I try looking up.

Good extension, but I really need it in dark mode :(

It works great on some websites but inexplicably doesn't work on others, even though the extension says it "Can always read and change data on this website"

不知道为什么……非常慢……半天不出结果（不知道是不是我的问题）

It's alright. Wished it had English (UK) instead of just US

Need an option to DISABLE on certain URLS! Driving me nuts trying to edit text and double clicking text makes this pop up instead of edit the text box.

Can be perfect but aint :) LeftDoubleMClick - is OK - but ...maybe RightButtonDMC will be better, or any choice? LDMC collides with ...many! And what with links?

I keep downloading this ext because I love the prospect and I keep running in to the same issue once I have it downloaded where no matter what I do the definition bubble that pops up will not close at all. No matter what I do. Then I delete the ext, a few months go by, I go to the ext shop to look for useful things, download it, and start the whole process over again.

So many words are missing. Mostly useless.

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.

I really want to love this extension. It's graphically pleasing, simple to use, very uncomplicated... but it's surprising just how many words I seek that it cannot provide a definition for. For that reason, after a year or two of using it, I have to find another with a more complete dictionary.

Looks nice but unfortunately it's US Americanized English only.

"my language"... for English it's English (US) only. Not good enough.

Doesn't respect language choice. Even though I set language in English, it still shows me defintions in German, when I click on German words.
