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

extension works great, any failings literally impossible to fix (doesn't work on pdf.) only bug i've encountered is the popup doesn't go away if you use it on tumblr/post/new. otherwise perfect.

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.

Second word searched: "Approved".

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".

Works great, gives definitions as it's supposed to. Overall makes reading for a non-native person easier.

I just love this. Granted once in a while i come across a word it isn't familiar with, but that is rare. Also it pops up at times i'm right clicking for another reason, but that too is rare. It is simple to use and i love the pronunciation option to actually hear how the word is pronounced.

Works well, but has a thin vocabulary.
