block flash object/javascript/3rd image.

I am not sure is it network problem?

I want to block flash object/javascript/3rd image.

I used FireFox 17 / IE 6

if flash (I disable that flash plugin)
but javascript, if disable, need loading that javascript content. I can't see it.
and 3rd image, only load/unload selected, no choice.


I used mobile data plan (limited), but is look some website content loading very long time and that website content volume(kb) very large.

any advice how to block javascript but can get javascript content and block 3rd image or released that image(I am control,view or not?
