The PERFECTO. It just works like magic.

It's using a lot of CPU even when it's idle. Approximately around 60% CPU usage increases when I activate this addon.

Came here after dictionary everywhere or anywhere (whatever it was called) went down. Better if not perfect replacement.

It works fine in general, but on some websites, like Instagram, the bubble doesn't disappear unless I reload the page.

Works perfectly but you should read their privacy policy, just in case.

This is a new must-have for me. It's easy to use. Looks great. and all around incredible to have installed with your browser

Amazing addon, and very customizable. This is now a must have for me

everything you want from a pop-up dictionary

Works beautifully Thankyou.

Knows a lot more words then the competition and has more options to boot. 5 stars

It's good, but the main concern is that it lacks supervision from the Firefox team. I hope that will change soon.

This Add-On does work very well! Has a nice ability to modify settings and tailor to one's usage. Only "tweak" that I wish it had, an ability to export/import settings.

This extension is awesome! Its like 3 extensions merged into one. My only problem with it is that its not open source and not having been reviewed manually by Firefox and given the Recommended tag as it could cause a security risk.
Edit: I don't know why but the Google search option isn't working. When I select it, it just gives me "If you're having trouble accessing Google Search, pleaseclick here, or sendfeedback.".
Edit 2: the error above is fixed but google search brings a captcha every time it opens.

it's just... so peak...

Nice attention to detail. Good job dev <3
