I used to like Tab Mix Plus but I found it’s just way too heavy compared to what I actually need and it very often slowed down my Firefox and made youtube videos etc. skip a few frames every 10 seconds or so, once Firefox has been running for some time.

I got tired of it and unstalled it, never looked back – Firefox is running much faster now :)
