Love it!

Checks out, what I can't see in CSS.

Awesome! Very Useful! Love It! <3

I'm a developer and I use the extension to test stylesheets and to inspect exceptional typography I encounter. It has become an essential tool in my daily workflow.

Very good!

Ultra pratique, complet, indispensable…

After the latest firefox update, it stopped working :(

Amazing works well for me! Good job!

Helpful and useful tool.

Excellent, worked for me. Thanks :-)

I love this extension. However, lately I can't get it to work right on Firefox Developer Edition. It works fine on Firefox Stable. On Dev, when I click text, the window pops up but is completely blank with no information where normally all the text CSS properties would be.

Otherwise 5/5

Great

Very handy for its purpose!

Such a handy tool for designers who are always looking for new and old fonts to use. Great add on! Works great.

brilliant!
