That was nowhere near what chrome does. This is why I have trouble taking Firefox haters seriously. A 1 time thing that they the haven't done again. Installed an add on that was never enabled or did anything at all unless you went through the trouble of enabling it. Needed you to have the Firefox studies checkbox enabled which all of us who would even care turn off first thing.

Chrome: no blocking ads on websites whatsoever. The comparison isn't even close.
