I can heartily recommend µBlock as well, it's low on resource usage (much lower than abp) and blocks nearly everything. I do tend to combine it with ghostery/disconnect to be extra sure (not that ghostery is developed by an ads firm, though they say their opt-out options is legit).
I didn't realize this was on for me. But to tell you the truth, I have never seen any of these advertisements. So either they were so unnoticeable/rare or they really were completely non-intrusive.
