I was turned on accessibility service on developer tool but I cannot turn if off. The turn off button said

Accessibility service cannot be turned off. It is used outside Developer Tools.

From this link said that

Once the panel content loads, you can then turn it off again using the Turn Off Accessibility Features button available in the top-left corner, unless you have the accessibility engine running previously to operate a screenreader, in which case this button will be disabled.

The button is gray out (disabled) and there is no accessibility engine running.
How to turn if off or only disable via the privacy control?

Does this work?

  • Click the menu button and choose Options.
  • Select the Privacy & Security panel.
  • Go to the Permissions section.
  • Check the Prevent accessibility services from accessing your browser checkbox.
  • Restart Firefox.

  • Thank you but that is **disable** via privacy control. From this link ( https://developer.mozilla.org/en-US/docs/Tools/Accessibility_inspector ). It said "Once the panel content loads, you can then turn it off again using the Turn Off Accessibility Features button available in the top-left corner." But the turn off button is gray out. Or there is only option to disable via privacy control? – vee Sep 10 '19 at 18:56
