I use Tor every once in a while for basic web browsing just to add some regular traffic to the network and not just dark web traffic. I mainly use it for Reddit as they lock to block me because of my VPN IP but don’t block Tor IP and occasionally other stuff. I know Tor is made so that everyone looks the same but, I am not really concerned with that when all I’m doing is browsing Reddit (my threat model isn’t high enough to use Tor for the purpose of getting Tor anonymity, at least for Reddit), so would using an extension like Dark Reader just to make it easier on the eyes gonna really have a big impact?
sounds like XY problem
you can use libreddit instances with your vpn ( for convenience you can install the libredirect plugin in firefox or whatever, just make sure to go to the specific reddit settings in the plugin, ping the instances and add only the ones that are up. The default one has been down for a while. )
this is the way. redlib is 100x times faster and better, and the probability that the instances are collection your tor browser fingerprint is almost 0%. Also i think there are some onion based instances?
