1385835 - WebExt API for URI parsing using the nsIEffectiveTLDService

Status: RESOLVED DUPLICATE of bug 1315558

(WebExtensions :: Experiments, defect)

Description

[tumpio]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0
Build ID: 20170630112252

Steps to reproduce:

I require same-origin policy detection for controlling third party requests with my extension. I would like to use the nsIEffectiveTLDService for it but it is not available for WebExtensions.

My requirement is to get the base domain of a request and compare it to the origin's to detect if the request is a "third-party" request. The nsIEffectiveTLDService has a method for "getBaseDomain". It was also previously advised to be used with Legacy add-ons:
https://developer.mozilla.org/en-US/Add-ons/Code_snippets/URI_parsing#Grabbing_the_main_domain

Have there been any previous discussion about this? Is any interest to make this service available for extensions? And is it possible to write an experiment API for it?

Sorry, forgot to mention that if you are interested in working on this, please feel free to take that bug, though the desired solution is to provide the api through WebIDL, which is a bit more involved (and means C++) than a webextension experiment.
