I used to use a plugin for firefox that lets you group tabs together and view them all on a kind of map screen.. That worked really well, but then firefox removed it about 6 months ago.. So now I am a bit lost I have to admit. I might go and look for a replacement for the 'tab groups' plugin now actually.

You can get a 1080p 24" monitor used on ebay for almost no money at all... They are hard to give away sometimes!
