1496679 - On Youtube, the page action "Add search engine" is always proposed even when the engine is already installed

Status: RESOLVED DUPLICATE of bug 1457069

(Firefox :: Search, defect)

Description

[Franck (Wip)]

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0
Build ID: 20181001155545

Steps to reproduce:
  - go to https://www.youtube.com/
  - click the Page Actions button (triple-dots at the end of the URL bar)
  - click on the "Add Search Engine" item (having the Youtube icon)
  - a blue popup "Search engine added!" quickly appears 
  - click the Page Actions button again and observe the available items

Actual results:
  The item "Add Search Engine" is still available despite the engine being already installed.

  Clicking on "Add Search Engine" a second time displays the following error message:
    "Firefox could not install the search plugin from “https://www.youtube.com/opensearch?locale=en_US”
     because an engine with the same name already exists."

Expected results:
  The Youtube search engine should not be proposed to be installed since it is already.

I tried other sites as https://www.amazon.com/, https://developer.mozilla.org/ or Wikipedia with different languages such as https://fr.wikipedia.org and everything works fine.

Maybe the bug is on Youtube side having a buggy search engine manifest/description.
