Original question, [http://example.com Why doesn't DarkReader add-on work on home page]? Answered [https://support.mozilla.org/en-US/questions/1235886#answer-1160324 with]: Internal pages are protected from addons. But you can simply select the dark theme in ≡ -> Customize. Possible reasons not to work: # The poster was an alien # 42 (See no. 1) # Mozilla devs just hate us. When we (have to) come for answers here, from a comfortable dark web - whether using Dark Reader, or some other means - they purposefully BLAST us with bright white pages so that we will never, ever use Firefox again and uninstall it right away and move on to something else (less idiotic). # Seriously, though, [https://support.mozilla.org/en-US/questions/1235886#answer-1160324 ''see the answer in context''] was an alien. So, who can tell us how to get around this, please? We get it, whatever: support.mozilla.org is, somehow, a local page - or, something - and it can't be styled, but how do we get around this BLINDING WHITE LIGHT? Thank you so much. ^^ addons.about ("addons.about-scheme") can be styled, Library (Downloads) can, Options (about:preferences) can and also about:about and a bunch of abouts can, also - only this website is locked like this, to torture people, why... EDIT: Screenshots attached illustrate that, as suggested in the first thread from years ago, Dark Theme had been applied and it makes no difference.
