Firefox 4 is already blazing fast. However there are a few add-ons and tweaks (not many know about it) that will make your Firefox look better and make it faster. Please be careful when you change the settings as they might be risky if you are not careful.
I have listed a few add-ons that are common for everyone to have a really great browsing experience.
1) Ad-Block Plus: Blocks all the ads on Google, Facebook, and other top sites giving you a better browsing experience.
2) Better Privacy: Gets rid of all those cookies that track your activities.
3) NoScript: Afraid of harmful scripts harming your computer. Install this and leave the headache to NoScript.
4) Session Manager: If you want to save your tabs and access them later, session manager helps you do that very easily. Give it a shot.
