Makes this website look like muddy water but I use dark reader[1] for all my web browsing. Ironically the only place it doesn't work is on the firefox addon page.
for security reasons extensions cannot run on the mozilla addons site.
btw many years ago i made something similar to darkreader, for some users it may be faster and more reliable but i also highly recommend dark reader too:
