Site whitelist for fingerprint deception

[therainydev]

Description

Add an option to disable fingerprint deception for some sites.

Who's implementing?

• I'm willing to implement this feature myself

The problem

The anti-fingerprinting features, while useful for protecting privacy, can cause some sites to have visible issues. In particular, the #fingerprinting-client-rects-noise flag causes the lines in the Desmos graphing calculator to jitter around randomly at high speeds.

To reproduce the issue:

• Enable the #fingerprinting-client-rects-noise flag in Ungoogled Chromium (via chrome://flags).
• Go to any Desmos graphing calculator URL, like https://www.desmos.com/calculator/gwqlodfcbm.
• Watch the lines jitter around in a very irritating manner.

Possible solutions

I suggest adding an option to whitelist some sites from fingerprint deception, which would allow users to disable fingerprinting deception for some sites while keeping it enabled for all other sites.

Edit: The specific issue mentioned above has been fixed in #2790. Nonetheless, adding a whitelist for fingerprint deception is a good idea because it would allow users to temporarily work around similar issues that may arise, as well as issues only pertinent to specific websites.

@karachikorai
The original issue of the rectangles moving around weirdly was fixed by #2790. (Admittedly, me opening this was a case of the XY problem, thinking the get*ClientRects fingerprint deception itself was the cause.)
I'd like to keep this issue open, though, because it's a separate feature that could be needed (e.g. if sites start detecting fingerprint deception).
Shall I update the original post to make that clear?

Yes, please be so kind, more so that one of the issues got fixed. A tight correspondence between issue subject and text would be nice.
