You shouldn't be doing that
There is a lot I don't think I understand for points he is making.
He is complaining about auto updates but every browser does this pretty much, and has a little notification that you need to restart to update? This is a core feature of firefox that it will force you to update before going on... this is a good thing for the general user .. not the niche user maybe?
I don't understand his shilling of Pale Moon, as it seems he doesn't like mozilla but Pale Moon is based off Firefox?
The cloudflare thing is kind of funny too. He says that because the ticket was deleted (do we know if by user or by the org?), that it is a conspiracy with CloudFlare to target Tor users. He is simply saying that Tor users shouldn't use any site that is in some way supported by CloudFlare (which 19% of the internet is "powered" by).
He is missing the fundamentals. Tor was not designed really for clear network traffic. If you are using Tor to clear network, you are pretty much gambling against the normal internet surveillance. He also misses the point that the developers tell you not to modify the browser because it's not some secret trying to control you, but that it makes everyone look the same. This is a common anti-fingerprint method.
Using Pale Moon with his discussion would make you easier to fingerprint instead of using a default tor browser install, despite how he feels about ad blockers.
To discuss the main subject, using tor browser as a main browser is not smart. It clears everything and you will be in hell solving endless captchas and be flagged constantly because of flagged exit nodes. Use Tor for intelligent reasons, in my stupid opinion.
