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

Firefox 57 geïnstalleerd maar die add on vertelt mij ik heb versie 56 geïnstalleerd. Dus, niet te gebruiken

ganz ok

Firefox earlier versions not compatible. Why???!!! A good application compatible the earlier version. This basic function.

Used to be five stars, but with the new update, it suddenly does the same thing that all the inferior capture plugins does when taking a full-page screenshot: simply scrolls the page and stitches the screenshots together. This causes tearing and additional effort which is completely unacceptable. Is there a way to restore the legacy version where it just captured the whole page all at once?

The addon shows dialog page after taking a screenshot (even if you turn it off). In the previous version you could save a page in one click, now there is always dropdown menu. Too much clicks, too poor usability. I'm going to use default Firefox screenshot option.

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

Fireshot öffnet nach dem Start von Firefox neuerdings eine Eigenwerbung. Deinstalliert.

I would give it no stars if I could. I've been using FireShot for years, but now you're installing adware with the upgrade so I have to look at your spam whenever I open Firefox. Also, the function of selecting the section I want to save is not visible anymore. I'm uninstalling this. It's a shame you had to ruin the free version to coerce people to purchase the Pro version.

Used with Nimbus, i love it

This add-on RARELY works - after choosing the method of capture from the drop-down menu, it's virtually impossible to select the area to capture. Attempting to start the process again is a waste of time because of the pop-up that reads the add on is still in use. I've removed this crap from my machine.
