Get a faster browsing experience by blocking nasty web resources using Bluhell Firewall, the lightweight Ad-Blocker and Tracking/Privacy Protector.
Here is a little more about the extension from the developers:
This is a lightweight extension (ie, 30KB compared to ~700KB of other popular adblockers), which was made with performance in mind. No configurable options, subscriptions, additional features, etc It just block what can go to hell ;-)
How this is achieved is thanks to just five hard-coded blocking rules covering about 7000 .com and .net domains, these were auto-generated from Easylist. That means, every time a certain resource wants to be loaded we will have to iterate through a list of five items, rather than for each entry from a common Easylist which contains thousands of different items to check… You can now figure things out for yourself…
You can pick up the Bluhell Firewall add-on from the Firefox Add-ons website.
