Comment Some Firefox suggestions (Score 2, Informative) 450
I have a couple of suggestions for Firefox...
Don't load images: Preferences -> Content and uncheck "Load images automatically".
Block other media you don't want: FlashBlock, AdBlock, QuickJava (for Java and JavaScript)
You could also try fiddling with the browser.cache.check_doc_frequency in your about:config. I haven't tried it, but setting it to 2 might yield good results.
