TAAR is extension recommendations in the "Add-ons Manager" (not sure how it's displayed)
CFR is extension recommendations as you browse the web, via a drop down panel
- description needs to stay changed from just cookies since it also clears site data
- keep the info about n days out of it, it's just messy (ESR users should be on version 60)
- get the values correct (I mixed them up earlier)
- fixup [setting] path
- leave in one (of two) extra [notes] I previously added
whatever we thought it may have done in the past, it doesn't do that now as far as we know. And it's not an issue since we allow extension update-CHECKs anyway.
regardless of this pref setting: the permissions.sqlite file will still be abused to store a flag for this for every single site you connect to (as third party?) - fun.
* clean up "Firefox Data Collection & Use"
- telemetry prefs to 330's
- Firefox Data Collection & Use prefs to 340's (but leave crash reports in 350s)
- move `app.shield.optoutstudies.enabled` to 330's - this is an internal pref which controls if you get the system addon
- make notes that `datareporting.healthreport.uploadEnabled` controls studies and ext recommendations
- split crash reports better to reflex the UI setting
`browser.urlbar.maxHistoricalSearchSuggestions` is default 0 is FF60 thru to FF66. It is also default 0 in ESR60.1 thru 60.5. (at least on Windows)
IDK if this has ever been used, maybe android, in which case it's probably useful?
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;}
```
might as well add it: needs t be taken into consideration when looking at the whole http2 thing. Will be interesting to see what Tor Browser does with it in ESR68
