I need help with my anti browser fingerprinting setup

I cannot afford to pay for an account isolation solution like multiloginapp right now so I am trying create a setup that can do everything that the paid solutions can do or at least get pretty damn close. To that end i have decided to go with using a separate chrome profile per account, it does a nice job of keeping everything from cookies down to the browsing history completely separate from other profiles which is better than the firefox container extension from what i can tell.

Lets ignore the issue of IP addresses for now and assume that there is no way to link accounts in that way.

Can anyone suggest the best extensions and/or free applications that i can use in order to change things like host OS, user agent and the whole raft of other identifiers that sites will use to try and fingerprint your browser ?
