Doesn't Work Rated 1 out of 5 stars

Recently installed this add-on as I was looking for a define tool which doesn't open in a separate tab, but I tried right clicking on the word and there is no option of 'Define this' there. Would be helpful if the bug is rectified.

There is potential, although.. Rated 2 out of 5 stars

Judging from the available image, this is exactly what I'm looking for- a discrete pop-up with the definition within, in contrast to similar add-ons that open in a new window/tab. Unfortunately, no menu option to "Define this.." is made available post-installation, and I can't find a way to access the options- if any.
Apologies for posting this here, I looked for a way to directly contact the developer to no avail- I'll keep an eye on the add-on and as soon as the issue is fixed I will re-review and re-rate.
Thanks for your time dev!

Currently very glitchy; "Define this" appears in the right click menu and as a toolbar button but the toolbar button shows like a box and both do nothing when you try clicking them.

Define this.. Rated 4 out of 5 stars

Good definitions, Can you have an option to double-click word to define it?
(1 less step to get to definition)
Keep up the excellent work!

This is a dead simple and really useful way to quickly check the meaning of a word without leaving the page.

Much better than cutting and pasting into!
