Firefox is a attempt to placate the original citizens of the web whos tools subvert the add surveillance industry .Google is clever enough to know how full blown antagonism to developers ends up. Oh and monopoly laws.
I'm against all those things as well - the only notable difference being that security lapses in the name of "social activism", in a leading browser than millions depend on for more than they should, is simply not permissible to me and many others.
The also impossible delineation between "socially activist ad" and "politically convenient" one make it a tainted resource, both security-wise, and bias-wise.
It is a organization, with no integrity; merely another institutional-preserving husk
I only use Chrome for compatibility reasons. Than I switch back over to Firefox.
Challenges are separating myself from the synchronized data universe that is the Google ecosystem. Passwords etc.
Definitely possible. Definitely worthwhile to retain control over my time.
