May I ask why you use both FlashBlock and NoScript? I haven't looked too much into the former but it looks to me to just have a subset of the functionality of NoScript (which I do use).
On a few sites NoScript causes the whole web Page to go nuts. So rather than dig into what element is causing this I disable NS and fall back to the protection of FlashBlock (Which is doing something simpler).
Browsing for anything other than a few minutes without these is impossible for me anymore.
