Hallelujiah! I have been looking for this feature for a long long time! I typically have to do multiple screenshots and clip them together in Photoshop. Or find a site that will do it and most are not very effective. Thank you!!!1

Good and fantastic

FireShot is normally a 5 star extension. But why has it become incompatible with earlier version of Firefox and clones (Waterfox, Palemoon, Basilik...) that are still used as Firefox Quantum does not support many essential XUL extensions.

I update my post as I eventually found a link to retrieve previous versions of FireShot, the latest compatible with non-Quantum Firefox:
https://addons.mozilla.org/fr/firefox/addon/fireshot/versions/?page=1#version-0.98.93
(Disable auto-update in the Options)

good..but not support

nice - love it!
easy to use

awesome!

Problems with the new version of Firefox have been fixed
As I promised, I gave 5 stars
Thank you

Used with Nimbus, i love it
