What I would like to do is to get a live view (in real-time) of the javascript state of a live website, and be able to change it manually. Including variables, timers, etc. I need this because I use a website to watch videos on, but the website auto-refreshes every 5 minutes and the video restarts from minute zero every time. I cannot disable javascript because the video won't play at all. Is it possible to see all the "active" variables and objects with Firefox and tweak them, for example change a timer?
