Thank you, Manuel! I registered a Mozilla account, after decades, just to be able to tell you that. Longer story:

As an Android Firefox (Fennec) user I grew increasingly frustrated and jealous of Chrome users who could so easily use the built-in Android long scroll screenshot capture feature that "just worked". Apparently Mozilla has classified this bug/feature as essentially "won't fix". Foolish - the feature is right there in Android now, but it just doesn't work in Firefox. I wanted to share some recipe pages with photos, and often the Print function in those sites strips the photo right out. Without a Google account (by choice) and an allergy to ads, the only thing I found was Stitch on F-Droid. It's fine, but has no scroll capture at all. Everything is manual and quite fidgety to accomplish what native Android provides in a tap.

Finally, I almost accidentally found your plugin. I added it to my Fennec and boom, a full page long screen capture, easily and within 2 seconds. It's like, perfect. I think your modest ("very simple") description undersells the value here, especially since Mozilla is so lacking and there are so few alternatives.

I've used it exactly once so far, and was impressed enough to register and peck this out on my phone. Well done. Thanks!

I added this trying to replace Screengrab which appears to have been deleted on this site, however, its lesser to screengrab in that it doesn't actually have a good interface for selection copying and it doesn't allow scrolling the page to grab a selection taller than your screen. You may as well just use Print Screen key.

As Firefox currently doesn't support scroll/full page screenshot on Android, this extension is really useful. It simply just works.

To me, the only Screenshot Addon that really works (only tested on Firefox Desktop Version!).
It does what you hope for:
1 continues, big picture - in a small fileformat - without external servers - advertisements - or a heavy addon with several megabytes!
Sleek - working - FOSS - I love it!
Thank you Manuel!

still the best, simplest and versatile screen shot saver, many thanks to M-Reimer

installed it with latest android firefox, tried on my ditect ferries booking page, it did not save whole page no matter which option i choose. it does work better than 2 other similar extensions i just tried.

Doesn't take a screenshot of the whole page, it just nothing more than what you can already do with your power and volume down buttons.

The add-on it's absolutely amazing.but the problem is that the Firefox already has a screenshot

This add-on work incredibly well on Firefox for Android!
A must-have add-on before FFfA has its built-in screenshot feature like the desktop version.

Mozilla Firefox 135.0b1 — OK.

Leider funktioniert "Ganze Seite" nicht, es passiert das gleiche wie bei "Anzeigebereich", es wird nur der sichtbare Teil als Grafikdatei gespeichert.

Wenn Du mir antwortest, kannst du mich auch ansprechen, statt so zu formulieren, als würdest du über jemand Unbekannt vom anderen Ende des Globus schreiben.

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).
