2711 is about web extension data and does not fit in the 2700s is all about websites' persistent data, i.e items that sanitizing and Storage Manager deal with. Dumping in 2600's which is getting a revamp later
* Options> and [settings]
While I'm at it, I'm changing the 21 instances of
- `[SETTING-56+]` to just `[SETTING]`
- `[SETTING-ESR]` to `[SETTING-ESR52]` because we'll leave those in until 62 (yes I know they may apply to earlier ESRs, but people should be upgraded). Thus no ambiguity with ESR60 vs ESR52 users for the overlap
This is so wrong: It is better to inform users that 3 **must** be used than rely on zero info as well as removing useful info on what the values do. All future issues with this will be directed to earthlng. Remove RFP info as RFP users should know this stuff if they turned it on. Non RFP users, who we told they can bypass it, will not have a reference to RFP now. Enforce will now be banned as a word because, "reasons".
add `browser.storageManager.enabled` back but enforce it as true - otherwise people may never pick up on the fact we dropped it and may never reset it, and never see their shiny new UI section. When it's deprecated, *then* we can remove it
pref will be removed, 99% sure it was just a pref used internally to hide it from stable during testing in beta/nightly - see https://bugzilla.mozilla.org/show_bug.cgi?id=1428306. Makes zero sense to hide this new UI section since we will be turning SM on anyway (the section is important for end users to exist and be working esp thru QuotaManager and Storage v2 changes etc).
note: picked up a leading space on 2206. Please double check for any errors or missed opportunities (I scanned it three times), 1221 is about the only one that's a bit messy I think
