Just about everything in this latest update doesn't work properly, takes longer to work and/or has lost functionality options. I was about to start donating because the app has been brilliant, but now there's no point. It needs to revert to it's pre-"update" version!
NOTE: I found Version history here: https://addons.mozilla.org/en-US/firefox/addon/nimbus-screenshot/versions/
I have re-installed 9.1.1

Why break it? This WAS a wonderful Add-on! What happened!? Are you trying to monetize your product by sending the captures through you site? Seems like something to do with money, somehow. Page scroll on capture is pointless. And this was only functional to me when it copied the image to clipboard or saved locally (automatically!). So disappointing! Don't bother until they roll it back to the previous functionality. Add-on removed!

Se instala pero no captura nada ayudenme por favor tengo la última versión de firefox. debería hacer capturas dentro del navegador pero nolas hace..

Not only did the point release erase the saved settings, but full page screenshots now have a totally unnecessary "animation" as it crawls down the page. So a screenshot now takes 3x as long for no good reason. Also, I've looked everywhere and can't change the one-click save location back to my Desktop like I used to have it, there's no directory option in the settings.

es la mejor de su tipo, muy fácil de usar y una ves que lo empieces a hacer te será indispensable.

Worked beautifully until 55.0.3, but now doesn't work at all.

La uso día a día y realmente es muy útil. Espere ansioso la nueva versión compatible con Firefox 57 con soporte para multiproceso.
