Click the three line menu button, click Preferences , and select Privacy & Security

James, I'd already read that and the toggle switch does not show up when I want to turn Enhanced Privacy Protection back on. This is the section I'm referring to: 1. Click on the shield  to the left of the address bar. 2. Toggle the switch  at the top of the panel.  
 ◦ This will turn off Enhanced Tracking Protection for this site. The page will reload automatically and allow trackers on this site only. Follow the same process to turn Enhanced Tracking Protection back on.

The last sentence to follow the same process to turn it back on results in no toggle switch at the top of the panel to turn it back on.

I hope that makes sense.

Can you attach a screenshot of the opened shield menu? Thanks.

Hi, we've sort of resolved this for now. Thanks for your offer to help!

Note that if you make the Firefox window too small that some elements may fall off on the about:preferences page.
