@vkc @trezzer I mean, in order to prevent screwing up my documents, I have to (a) download a new package and then (b) dive into about:config and flip the boolean for middlemouse.paste. There should be one toggle in the plain old Settings box. I wouldn't care that much about what the default setting even is; the problem is that the simple toggle *does not exist*.

@vkc @trezzer I have *never* used middle-click-to-paste deliberately. It *always* gets me accidentally when I tap a laptop touchpad 0.5 centimetres in the wrong direction. That I have to turn it off separately in GNOME and in Firefox/Librewolf irritates me to no end.

@djamilaknopf Good luck!
