While it does seem to work well, I was unable to get the icon to appear on any of my toolbars on separate computers. And with no hotkey, if you are screen-shooting a few tabs at a time, it's not any more convenient than clicking through the Firefox screenshot option. The only advantage seems to be the "full page" feature which most people would probably use the fewest amount of times.

Addendum: I was planning on changing this review today, as I reviewed other add-ons I also started using yesterday. Then I saw the developer response, and thought I should hurry before they get any more irate.

I did know about the "pin to toolbar" option for the add-ons. However, when I first tried it, the icon still did not show up on the toolbar. It wasn't until later that I noticed that others weren't showing up either after trying to pin them. So, I removed those add-ons and reinstalled them. Then it worked. This was a brand new profile, so maybe some bug or something that came with an update? I don't know.

As for the shortcut key, I also noticed that the keys for this add-on was in conflict with another key, which I thought was the problem. But after removing the conflict - and then reinstalling the add-on - it still doesn't work. Another bug? I don't know. In any case, I raised my rating to four stars since, as discovered, this was obviously issues with Firefox itself and not just the add-on.

Perfekt.
Ich musste einige Add-ons ausprobieren, und das hier macht Screenshots ohne lästige Nachfragen. Klick und fertig ist der Lack.
Danke Herr Reimer

simple and efficient

Works even on Firefox for Android.

one of the best screenshot extension for firefox till now.Is it available for chrome too?

alles gut

Works good until you try a "selection" with scrolling... Doesn't work in these cases.

best thing about this extension is simplicity.no screen popups or new tabs to edit screenshot.
Good work keep it up !
just introduce hot keys. so there would be no need to click on extension and select from list. -OR- just introduce priority option in extension setting. so that just click on that camera icon and screenshot captured according to settings priority.

Extensão boa para Firefox de Desktop e que pode ser instalada no Firefox para Android. Á de melhorar a interface para se adequar a resolução de tela do navegador na versão Android e corrigir bugs das funções de captura parcial e completa do site quando se marca a opção de 'mostrar a notificação de conclusão da captura' fazendo com que a captura não funcione.

Muito obrigado por ver meu comentário 👍. O visual da resolução da extensão ficou muito boa, além das funções de captura estarem funcionando bem no Firefox para Android. Tomara que logo esta extensão entre no catálogo da AMO para Android. E que você desenvolvedor, continue assim se empenhando sempre, saúde e paz para todos nós. 😄✌️

Die Qualität ist besser geworden, oder??? Habe noch zusätzlich den "Fireshot" für bessere Scrennfotos installiert, aber ich glaube den Werbe-Shot kann ich jetzt runterschmeißen.

Понравилось. Можно настроить под свой вкус. Спасибо. Самое удобное из всего, что попробовал в расширениях для мозиллы.

Complimenti, un programma intuitivo ed efficace; se ci fosse lo Scrolling Screenshot sarebbe perfetto.

Enfin une extension capture d'cran qui fait ce qu'elle annonce (totalité de page). Efficace et simple Parfait !
