> I have an older mac with older FF. Results: librewolf and waterfox wont run (10.15 min) That's just because Firefox itself requires at least macOS 10.15. IceCat only works because it's based off of Firefox ESR; once the next ESR comes out IceCat won't work either. There is a fork of Firefox (which is in fact the web browser I use) that adds back support for older versions of macOS. At the moment, it supports all the way back to OS X 10.8 Mountain Lion. However, this is all it does; it does not contain any additional privacy features above and beyond mainline Firefox. However, I guess it technically isn't a Mozilla product, so you won't need to agree to Mozilla's Terms of Service. https://github.com/i3roly/firefox-dynasty/releases https://github.com/i3roly/firefox-dynasty/releases
