There's a firefox extension called "Privacy Settings" that I was able to
install on abrowser that gives instant access to some important privacy
settings:
https://addons.mozilla.org/en-US/firefox/addon/privacy-settings/?src=search
It's not in the abrowser culled list of libre acceptible extensions. It's
licensed under Mozilla Public License 2.0. FSF website posted an article
saying that MPL2.0 is GPL3 compatible - is that still accurate?
Maybe it could be reviewed for possible inclusion in the abrowser list of
acceptable libre extensions. Github is here:
