no need another add-on

Does a good job and is helpful to quickly find out what font has been used in a web page.

Very good , Very Fast to find the font of any website. Tks very much.

Amazing. Bravo!

Excellent !

It works but I think it doesn't nescessary to open a new window, just an inline popup would work better and I could just press Esc to close.

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
