Using two different lists at the same time

[NightEagle]

Can I use two different blocklists, example EasyList and Fanboy list at the same time without problems?

It depends what you call "problems". I would not recommend it as there is a higher chance for false positves and half of your rules will be useless as both lists (fanboy and EasyList) generally cover the same sites/ads. And although Adblock Plus does a pretty good job in handling rules as fast as possible, it still makes a difference whether you use 12.500 rules (1 list) or 25.000 (both lists). It's better to just use 1 list unless there is a very good reason for it, don't just do it because you assume adding 2 lists will block much more ads, the amount of additionally blocked ads will be very small and at the same time the chance for issues increases and the performance decreases (but not much).

Anyway, now that you've been warned, there are a few people here that use EasyList and fanboy's list at the same time and they are happy with it, so you might just want to try it as well if you think you need 2 lists.
