HOW TO ACTIVATE DIMX
DimX only recolors a site that is already in its own dark theme. It changes that dark theme to Dim navy (#15202B). If a site is in light mode, DimX leaves it alone by design. No account or sign-in is needed.
If a site still looks light, it is in light mode. Switch it to dark using step 3.

- Install DimX.
- Reload every X, X Pro, Grok, or Reddit tab that was already open before you installed DimX. New tabs work right away.
- Switch each site you want dimmed to its dark theme:
- Easiest: set your browser or operating system to dark mode. Signed-out X, Grok, and Reddit follow this setting, and Grok follows it when its theme is on auto.
- Firefox: Settings > Appearance > Website appearance > Dark.
- Windows: Settings > Personalization > Colors > Choose your mode > Dark. macOS: System Settings > Appearance > Dark.
- Grok: click the gear icon at the top right, then click the moon icon.
- X and X Pro (signed in): More > Settings and privacy > Accessibility, display, and languages > Display > Background > Lights out.
- Reddit: set Display Mode to Dark, or leave it on Auto (the default) and use the browser or system setting above.
- Open or reload the site. The black or dark gray background is now Dim navy.
- Click the DimX icon in the toolbar to see one toggle per site. All toggles are on by default. Turn a toggle off to restore that site's original dark colors, or on to bring back navy. Changes apply right away, with no reload.
If a site still looks light, it is in light mode. Switch it to dark using step 3.
