i'm concerned about this as well, but i'm fine letting Chrome function simply as a dev tool and actually browse with Firefox, Opera, Servo, etc. w/uBlock Origin & uMatrix
And here's some more history: https://hacks.mozilla.org/2016/12/firebug-lives-on-in-firefo...
I'm definitely in the same boat. That makes me wonder if it would be a bad long-term move for Chrome. Just guessing here based on personal anecdata, developers are more likely to use ad blockers, which could alienate the developer community. If that's true, I wonder if we would see a resurgence in Firefox and other browsers.
