Hello and thank you for your help.. I have the newest version of Firefox. I added several Dark background themes, what i am trying to make happen is no matter what Website i go to the back ground of that website will stay Dark. Like this website has a white background.. I am getting older and the bright white back grounds of a website is hard for me to few with a white background, How do i make it so no matter what website i open, the background of that website will be Dark like the theme i downloaded and picked for my default theme..Thank you for you time and help.Scott

Firefox comes with a built-in dark theme for the user interface and for most (or all) built-in about pages. There are also more monochrome Colorways themes available and you can possibly create your own theme.

For webpages there is support for @media (prefers-color-scheme:dark) support that webpages that support dark mode can use. For other pages you can search the Add-ons website for a suitable extension.

Note that extensions do not work on most Mozilla websites for security reasons as Mozilla websites have special privileges. To style those pages you would have to use code in userContent.css.
