The newly updated version finally works with the latest version of Firefox!
I hope they will keep it updated as they do with the Chrome version.

Minus one star because the addon is not part of the Mozilla's Recommended Extensions

Blurry imgs

Doesn't capture the entire page, at all. Don't waste your time.

Really useful, especially because creating images that keep the page name

This is good screen capture with some useful editing tools.

The new thing I found about the 'capture entire page' option is that if you jump to another tab after selecting the option 'capture entire page' it will capture that page in background instead of cancel the process.

Incredibly helpful and timesaving

Excellent

Funciona muy bien y las opciones que da son muy variadas. Quizá se puede mejorar la captura de una web entera, ya que genera mucho ruido y unos scrolls, en algunos casos, demasiado largos y añadir más opciones en la sección de la cuenta del usuario.

Em alguns casos, o resultado ainda não é o ideal. O conteúdo da sobreposição (overlay) não fica perfeitamente contínuo.
