We really need "corporate bullshit removed" forks of both Chrome and Firefox.
IceWeasel and Chromium were effectively Firefox and Chrome without the (surface level) corporate branding. Chromium is soon having many of its Google tie-ins severed. Debian and Mozilla resolved their trademark dispute, so IceWeasel mostly went away.
These browsers are open source, yet they both suffer an unpalatable amount of corporate control. Google can do whatever it wants, because it's the king. Mozilla is able to get away with this because they are the only real alternative for people who don't like the king.
firefox: user.js repos (eg. https://github.com/arkenfox/user.js/ or https://github.com/ghacksuserjs/ghacks-user.js/)
chrome: ungoogled-chromium
