These are all at default values, no need to enforce. As for removing them, we're de-cluttering the section and these just aren't that important. Anyone who wants to play with tab ordering/focus/etc could probably use an extension (API's?) and/or easily find these and look them up
geolocation blocking via RFP will be removed (see https://bugzilla.mozilla.org/show_bug.cgi?id=1441295), and since either way you look at it (those who use RFP or not) the user.js blocks geo, so we might as well move this stuff back to section 0200
1376865 was back ported to 59, so canvas prompt fatigue will be reduced. Note: the default for non-prompts is the same as if you clicked "Don't Allow" - i.e it serves up a 10x10px white square
Cleaning up the UA spoof stuff in the sticky, as a ticket was just closed (52 is now a temporary hard-coded value: 1418672 - I guess they're running out of time), so also cleaning up the info, and consistent layout
Two issues: The code to determine the ESR number is out of whack (by one) since the next ESR is 60. 59 stable is almost here. So they have decided to hard-code the value as 52, for now. The second issue is that Aurora/Nightly are ahead of stable/ESR and can thus unmask themselves as Aurora/Nightly. The hard-coded value for now also solves this.
If you follow the sticky for RFP, you will see there is a ticket for using the update channel information (eg stable, beta, dev, nightly etc) to determine when and how calculate the version spoof in future, and they'll also rejig the numbering algorithm to account for ESR being out by one. These are tickets https://bugzilla.mozilla.org/show_bug.cgi?id=1418162 and https://bugzilla.mozilla.org/show_bug.cgi?id=1428111
These default values are the same in all OSes and all current Firefox versions (ESR, Release, Beta, Nightly).
Apart from alerts.showFavicons these defaults are most likely never gonna change
data: works perfectly fine here. No need to use https and no need to connect to localhost because something could be listening there.
data is the fastest and best solution.
Note: I tested the value of 1 when changing from 2-block to make sure that it actually changed to allow in the panel. Am keeping my eye on the delete and backspace keys and will remove the line when it is fixed
