@csagan5 Do you plan merging this PR?

PS: I've applied this patch over ungoogled-chromium locally and all client hints seem to be gone, including the JS hints.

PPS: https://browserleaks.com/client-hints does not detect anything, but https://coveryourtracks.eff.org/ does correctly detect screen size, platform, hardware concurrency and device memory.

does correctly detect screen size, platform, hardware concurrency and device memory.

this patch does not change the behaviour of the standard javascript api, by the way, the other patches do not change that information in any way either.
if you are interested in camouflaging (and testing :) screen size, try #2294

for the desktop version you need:

build for windows works without problems, I would like to understand if anything else is needed for linux

platform, hardware concurrency and device memory.

"platform" what do you mean? for the others we have nothing yet

I realize that, just wanted to mention, in case you wanted feedback and/or improve this patch further

"platform" what do you mean?

It correctly identifies, that I'm on "Linux x86_64"
EDIT: never mind, it could be easily extracted from user agent, duh :)

Thanks for pointing me there! I'll give it a try later and let you know how it works on Linux.
