I am a user of Tryahackme.com. Within THM you work with the website on the leftside of the browser, on the rightside you get an attackbox, normally a windows or linux machine. Ever since the latest update of firefox an annoying error was introduced, as soon if I hover over the attackbox it continiously creates an "PASTE"-option , even if I haven't copied something. It appears as soon as I hit my left mouse button. It actually creates an unworkable situation as the "PASTE"-option doesn't go away. I checked from an linux machine with the latest firefox and the error appears as well. I checked with Chrome and Edge, no error.
