I installed Fasterfox this evening out of sheer whimsy. It looked like an interesting extension. I don't find Firefox really slow, but it was worth a try.
I honestly didn't find a huge difference with any of the preset settings. Normally deviantART takes a long time to load. With the settings, it sped up marginally, but on average I think it's the same. ImageShack images, though, do load faster. ImageShack's servers are normally so darn slow to respond that it can take over 2 minutes to fully load a page! The content is accessible way before then, but it is still annoying. <Matthew the Ranting Maniac (:D) has already ranted about ImageShack's reliability, so trundle over there.
Other than that, though, I'm not noticing much of a difference. I'm not sure if I want to keep it or not. My technical knowledge isn't profound enough to know exactly what it does to my computer or the servers, but if I don't see any noticeable difference, I might uninstall it just because I like tidying up stuff that I don't use.
So, anyone have an opinion to share? :r
