1532314 - Add remote block list and remediation actions for overridden home pages

Status: NEW

(Firefox :: New Tab Page, enhancement, P3)

Description

[Tim Spurway [:tspurway]]

We currently use Remote Settings to store buckets of domains so that we can report (in bug #1494101) on what kind of overrides exist.

Let's extend this list so that we can also store remediation actions for those buckets. A remediation action will allow for specific actions to be performed when the URLs in the bucket are identified as the overriden about:home URL.

Here are some possible actions:

• OPT-OUT ADD-ON - force the reset of the about:home setting to the default (Firefox Home Page) without asking the user for those users whose homepage URL has been reset by a known add-on
• OPT-IN ADD-ON - prompt the user if they want to set their about:home back to the default setting (in a door-hanger) mentioning which add-on has caused the override.

Note that for the ADD-ON actions, we need to ban list the add-on to prevent it from re-overriding the setting again.

• OPT-IN USER SET - prompt the user if they want to set their about:home back to the default setting (in a door-hanger) mentioning what domain the home page is currently set to.
