Accessibility not available during multi-process support

Accessibility features are not yet fully supported in multiprocess Firefox. If third-party software (screen readers, Windows touchscreen software or anti-spyware) requests access to Firefox's accessibility features, Firefox limits this access to web content to prevent stability issues. Restarting Firefox will change it back to single process mode and re-enable accessibility features automatically.

How to re-enable Firefox's accessibility features

  1. To fully enable accessibility features after having received a notification, restart Firefox. It will restart in single process mode.
  2. To force enable electrolysis for testing purposes, go to the about:config settings and set the browser.tabs.remote.force-enable preference to true. Recommended for advanced users only.
  3. Avoid running third-party software that request accessibility features within Firefox.
