Nah it would make a big dent for sure.
Firefox has ~180 million users
Amount of users using adblockers is ~900 million.
It would massively change the market.
Numbers according to mozilla and statista
Im using Firefox because fuck Google’s monopoly, but Firefox seems to care little for some stuff I think is critical, namely AV codec support. Lack of out of the box support for HEVC and a few others, which my underlying OS supports perfectly, is a big turn off.
May be time to give Opera a spin
There are at least 3.45 billion Chrome users (not chromium, chrome).
Out of those ~900 million adblocker users, how many are using those adblockers that let paid advertiser’s to get on a whitelist? How many are willing to make an effort to change browsers? Firefox’s 180 million users is the indicative of this, and not all of them user adblockers, so the numbers keep getting thinner.
It wouldn’t make a single dent in Chrome’s dominance.
