Lightweight Ad-Blocker and Privacy Protector for 
Mozilla Firefox and 
Thunderbird.
All we know the availability of popular AdBlockers lying around... but frankly, these are too bloated with several features and options which most of us don't use beyond the defaults. So, this extension was made for those of us who don't care about all that stuff but does about just getting rid of all the nasty resources being loaded by websites. More Info »
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...
Next i'll let you decide if this is for you... as long performance is in your mind, it should.
You can turn the extension on/off at any time by clicking the toolbar button (Fx Desktop), or touching the menu item entry (Fx for Android)
