I think that list is kept relatively up-to-date.

More generally, there are a lot of customizations in Tor Browser to turn
off or alter Firefox features that might identify a user (by making one
Tor user's browser look recognizably different from others) or might
bypass the proxy (causing the browser to send non-Torified traffic over
the Internet).

The Tor Project hasn't received a lot of help from the Chromium developers
on changes that would be important for making these customizations --
but with or without that help, they would be a lot of work in their own
right, just as they were a lot of work on the Firefox side.

You can read about some of the customizations in the Tor Browser design
