and the rest of the 0850's

The location bar dropdown cannot be disabled via prefs except with css, in which case the whole thing is hidden regardless of he above prefs. So there is no point in making any of them active. This is also in line with what we can achieve with relaxed and hardened tags / sticky issues - that is we can find a better balance, Shoulder surfers is a low risk, not even Tor Browser disables this stuff. People need to take responsibility and/or use common sense. Sure, we can leave em in for users to know about and enable if they want. End of story.

userChrome.css code is
```css
/* locationbar dropdown FF65+ */
#PopupAutoCompleteRichResult {display: none!important;}
```
