Welp, it happened to me as well bros. I got the "completely unresponsive" bug where you can't click anything until you restart Firefox. I only had it once in the past when they first introduced the AI sidebar chatbots and I tried them out, but I have disabled every AI feature since and haven't had any issues. Until a few moments ago, where it happened out of nowhere. I was just watching a YouTube video and wanted to click the Extensions button and every browser button stopped working.
