Greetings All, first post etc.
Firefox has been my primary browser for a couple of years, but has recently become slow in operation, reason unknown. I have used Brave occasionally over the years, but my intention now is to use Brave as my primary browser, Brave speed is noticeably quicker.
My limited understanding is that it is not possible to create bespoke “dark mode” for Brave, is this correct? I can see:
settings → appearance → Brave colours = three choices of “same as Windows”, “Dark” and “Light” .
There’s also the option of “themes” from the Brave webstore, but I can’t see any theme that works for me 
Brave version: 1.76.74
