Inspector consoles opens and closes repeatedly

While I was using Firefox, the inspector console window started opening and closing all of a sudden. Whenever I try to click on a different tab that is not the one I am currently on, it switches back to my current tab. This issue also occurs on other Firefox-based browsers, and not on any other browser I have installed. I attempted to change the theme, I went into Safe/Troubleshoot Mode, disabling my extensions, etc, but nothing changed. I've restarted my computer twice already, and yet it doesn't seem to change anything. The only way I could temporarily halt it was through holding Ctrl, Alt and Shift at the same time, but this only worked for as long as I held all three keys down. What should I do about this?
