Mozilla Firefox 135.0b1 — OK.

This add-on is perfect. Although Firefox already has a screenshot feature, this add-on is very straightforward and offers various but simple options. I have it set to take screenshots in JPG format at 90% quality, and every capture comes out with excellent image quality and without much file size. Yesterday, I also discovered an option that lets you add the date, hour, minutes, and seconds to the screenshots exactly how you want! Thank you! :D

Work so good (Firefox mobile).

It's a add-on that does its job.

So helpful for firefox android! Please check it for security as well, Firefox team.

Es exactamente lo que estaba buscando. Funciona muy bien ya que guarda el sitio web tal cual como se en el navegador. Cuando hay partes de un sitio web que contiene un video, la captura puede tomar cualquier frame de éste, pero eso es un detalle. Muy buena la extensión.

So far, so good. I don't know if it has a shorter way to capture the screen, but you can choose from full, viewport and selection in PNG or jpeg. And the best feature is it names the capture! So it saves me from putting each name. Yeah!!!!

Enfin un module de screenshot qui fait juste ce qu'on attends de lui, et qui ne nous fait pas passer par 5 écrans pour avoir un simple screenshot de la page entière. Fonctionnalités minimales, on peut même le configurer pour exporter la page entière directement dans nos téléchargement sans avoir à faire plus que cliquer sur l'icone. Juste parfait.

Good enough I put the effort into making an account to leave a 5 star review. This is the only one I could find that does what it says it does and does it properly.

This works really well right out of the box. I configured mine to only use PNG and it's quick.. Naming convention is perfect.. I don't think it could get any better than this and should be added as a default plugin for FF. SICK AF!!!

Marvellous. Tiny (38k), effective and easy to use extension. It's what I was looking for. No horrible effect of scrolling while taking screenshot, plenty of configurable options for all the needs (naming, quality, target dir). Absolutely perfect!

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.
