The Internet is already awash with bots that do exactly this: visit sites and 'click' on all the ads. Fraudulent ad networks employ these bots to generate revenue. The adtech industry has already implemented software to ignore these clicks (it's pretty glaring, after all, when all the ads are clicked simultaneously when generally only one in every 500 ads is ever clicked.) This also does not corrupt the algorithms most adtech companies use by even a little bit. Weeding out the bogus clicks of people who would never, ever click on an ad anyway (because only those people would install this extension) does not in any way change the ability to project from the people who do click on ads. And, as others pointed out, by 'clicking' on the ad instead of just blocking it, you provide information to the ad network anyway. If you really don't want to be tracked online, block third-party cookies (or clear your cookies at the end of the day), and turn off flash. (If you don't want to be tracked offline, call your congressperson, and good luck.)
