Cons
Con Uses too much RAM
AdBlock+ tends to use a lot of memory, which has been documented in many use cases as well as admitted by AdBlock themselves. Considering there are alternatives out there that can block ads successfully with half the RAM usage as AdBlock, one has to wonder why this is a problem specific to AdBock.
Con Users automatically opted in to whitelist
AdBlock+ has an automatic whitelist when installed that allows certain advertisers through the blocking mechanism. The fact that these advertisers pay for this privilege makes this particular scenario rife with conflict of interest.
Con Iridium is currently on hold
The current build includes a bug which seems to break youtube functionality. However after a bit of searching, a solution can be found. Posted here to help others who might be debugging all their extensions for youtube not loading videos.
The solution for many seems to be to keep the autoplay function within Iridium settings ON.
Now your videos will most likely load and play again like they should.
