I see some users are having difficulties. The extension is working perfectly for me, though. I get a small popup for words I want to check and there's no page reload or redirect issue.

very convenient! good settings!
(lil feedback: if I were you I would tighten up the pop-up window margins & make dark mode darker🖤)

Expand your vocabulary easily. One feature I found useful was the Power Thesarus icon in your text. It would open in a small window for the top 10 synonyms and antonyms, with the with a link to more on their website.

Very useful Add-on, and simple to use without adding any clutter to the browser

Good Experience, This is what i was lookin for

I write long guides and emails occasionally. This tool is very handy in making the message more understandable, intelligent and professional. Great little non-intrusive extension. Thank you.

I'm learning so many synonym!!

Fantastic app. I've been using it for years now and it sure has helped me expand my vocabulary.

very good. thanks alot

Very useful extension -- now my everyday writing companion

It needs some more precise words, but is the only extension that works for this purpose in mozila

worked very well.

Great. It enables me write better now

Surprisingly compatible with Google Dictionary. Always room for improvement, e.g. more than 5 results at preview. Good.
