What Chrome behaviour regarding ad-blocking caused you to make the switch? Installing an ad-blocker with Chrome is just as easy as installing one with FF.
It points to news sources trying to get clicks using inflammatory headlines. Google has never blocked ad-blockers or announced that they were going to. They announced API changes which will require ad-blockers to change the manner in which they are implemented. What they recently announced is an increase in the number of blocking rules allowed under the new api which some want to call a u-turn by Google. Except Google announced earlier that the preliminary limits were likely to be increased later after performance testing, so what Google has actually recently announced is just in line with their earlier announcement. Of course that take on it doesn't follow the pitchfork mentality on HN regarding Google nor make for clickbait headlines.
