There's very little real world support of SPDY yet on the server side, so any "faster browing" is going to have to wait until it's actually more available.
Indeed, it's not clear that SPDY actually will speed up some websites (ones that are mostly a single large page, such as FreeRepublic, for one); it seems likely that the primary beneficiaries will be websites that have lots of trackers and other embedded bits that a server can guess are going to need to be pulled in for the full page.
Do Not Track Plus from http://abine.com/products.php is a good extension for both IE and FF that blocks trackers.
It is free for home use.
