Like I said in the subject title, I can't seem to type in the comments section of youtube without activating the shortcut key, ie: pressing the spacebar while typing plays/pauses the video, and the space does not appear, f toggles the fullscreen, m toggles mute, and other shortcut keys in youtube. I have tried firefox safe mode (add-ons disabled), and the same thing happens. This only occured today, and nothing was wrong yesterday. Commenting in youtube on other browsers, edge, chrome, and opera seems to be working properly. I'm using Firefox 86.0 64bit.
