Maybe you should try out "The Proxomitron" (download from proxomitron.org). It's a small freeware app acting as a fake local Proxy between client and server. Very configurable, you can filter pop-ups and banners, set javascript policies, block annoying applets and set bypass for trusted sites via a simple GUI.
Best: no need to install it, just copy it to program files and paste a shortcut in your startup folder. Then set browser to use localhost as proxy adress via port 8080. That's all.
I enjoy a clean browser window since I use it.
