I have albinism. Pure white backgrounds are not an annoyance – they cause physical eye pain and trigger migraines. Every time I visit support.mozilla.org or accounts.firefox.com, I am forced to endure #FFFFFF with no way to change it.
To anyone about to defend Mozilla blindly: this is about accessibility and eye pain, not brand loyalty, so do not silence me.
What Mozilla has done:
- Disabled extensions (Dark Reader, Stylus, Dark Mode) from modifying these pages – they are explicitly blocked by Mozilla's own Content Security Policy.
- Removed ui.systemUsesDarkTheme and layout.css.prefers-color-scheme.content-override from having any effect on these sites – they ignore prefers-color-scheme entirely.
- Left no about:config toggle to disable the forced light theme.
The only remaining workaround is a userContent.css hack with filter: invert(1) – which requires a visually impaired user to manually edit CSS files and restart the browser. That is not accessibility – that is hostility.
Security excuse – debunked:
- "We block extensions for security" – extensions are sandboxed. Blocking them on your own support pages is a deliberate policy choice, not a technical necessity.
- "We want a consistent brand appearance" – branding does not override accessibility. Forcing #FFFFFF on users with light sensitivity is a violation of basic inclusive design.
- "We respect prefers-color-scheme" – you do not. These two domains explicitly override it.
- "Users can just use Dark Reader" – you block it.
What I demand:
Make support.mozilla.org and accounts.firefox.com respect the system prefers-color-scheme media query.
If you insist on light branding, add an official dark toggle in the site header – stored in a cookie or account preference.
Stop blocking extensions from applying user‑chosen themes to your own sites. That is not security; it is control.
You are a non‑profit that claims to value accessibility and user control. Your actions say otherwise. Fix these two domains. No CSS hacking should be required for basic vision safety.
