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

Apesar de não ter o tamanho da fonte em PT, mas em PX... Vale a pena. Exibe com precisão em pop-up as informações como "Elemento", "tamanho" em pixels e um link para avaliar a fonte no site "Fonts". O menu de contexto funciona no Firefox 58 para Windows 10 com a opção Inspect Font ou Analyse Selection conforme a seleção do texto. A extensão é uma ferramenta útil por sua precisão e rapidez.

Would be five stars but it needs to have the Font Size in pt, not px as most designers work in pt. Also would be good to incorporate the em size as well as some designers use this as well.

Great

Very handy for its purpose!
