good but dont know the info given is accurate

No icon is visible on Firefox 61.0b11 (64-bit), so can't be used. Don't take this review too seriously -- it's probably a bug that I should have filed on GitHub.

....but wait! There it is in the address bar. Works great but you might have mentioned this little peculiarity.

very interesting extension :)

Pretty good :)

very useful for web developer.

Me sirvió para aprender mucho sobre varios temas de informática, no tenia idea de algunos lenguajes de programación por ejemplo

Excellent

Great tool. Thank you!

I can install this addon but the icon isn't show. I can't use this addon on firefox, on google chrome it's O.K.

My version of firefox : 58.0.2 (64 bits) Firefox Quantum
