Firefox Add-ons

My favourite Firefox add-ons/extensions.


AdBlock Tips
  • Before creating a filer, check if you can fine-tune the rule, e.g. adding a wildcard * might make it more generic, or blocking a whole domain instead of a subdomain
  • domain##div>a:has-text(/promoted post/): at domain, remove any <div> containing a link with text "promoted post".
Personal individual tweaks
  • Allow CORS with local file:// urls: about:configprivacy.file_unique_originfalse
  • Site Isolation on Firefox: about:configfission.autostarttrue (can check info at about:processes)
  • Disable media autoplay: about:configmedia.autoplay.default0 and media.block-autoplay-until-in-foregroundtrue
  • Force dark mode under Linux: about:configui.systemUsesDarkTheme1
  • Enabling DNS-over-HTTPS
  • Bigger scrollbar: widget.non-native-theme.scrollbar.size.override18
  • Activating ECH: about:confignetwork.dns.echconfig.enabledtrue and network.dns.use_https_rr_as_altsvctrue
  • Zoomed devtools: devtools.toolbox.zoomValue1.2
  • Don't auto-close browser if all tabs closed: browser.tabs.closeWindowWithLastTabfalse
  • Show UA styles in dev tools: devtools.inspector.showUserAgentStylestrue
  • Disable local development favicon annoyance: -> → false
