Have you noticed the ‘screenshot’ feature seems to have disappeared from Firefox?
The latest update has changed it from being a “Page Action” which is usually found in the address bar, to a “Browser Action” that now shows as an optional button for the main part of the toolbar.
You can add the button by choosing MENU>Customize Toolbar…
Alternatively you can right-click the mouse on the web page, and on the firefox menu that pops up choose > Take Screenshot
If none of those are available, try the following:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
(2) In the search box in the page, type or paste extensions.screenshots.disabled and pause while the list is filtered
(3) If the preference is bolded and has a value of true, double-click it to restore the default value of false
