I have a suggestion: Is it possible to hide the "Take Screenshot" option from the Firefox right-click menu?
I always take screenshots using the Print Screen key on my keyboard, so I don't see the need to select it from the right-click menu.
Also, there is an "extensions.screenshots.disabled" option in the "about:config" menu,
and I found a search result that said "You can hide the 'Take Screenshot' option from Firefox,"
so I tried it, but it didn't work, so I don't think there's any reason to keep "extensions.screenshots.disabled" in "about:config."
