Dear Mozilla.org please add it as default in the browser if you care about privacy and the web in general, This is the first add-on that I install on all computers , mine or for friends
That they've put off doing the obvious for so long ("obvious" because one of the key selling points of the browser at initial release was, de facto, a form of ad blocking—namely, popup blocking) makes me think we're more likely to see integrated ad-blocking in Safari than in Firefox. But probably neither is very likely.
