1467040 - All default search engines gone in latest non-en-US nightlies

Status: VERIFIED FIXED

(Firefox :: Search, defect)

Description

[Irvin (MozTW)]

Attachment: No search engine on new profile

Checked with latest zh-tw nightly (2018-06-05), the problem does not exist on latest en-us build. 

(1) All of the default search engines are gone. 
(2) You cannot click into search settings from preference panel, no response.
(3) Search related features are all broken, such as URL search engine or Search bar at home screen

If user upgraded from an older profile, the user-added search engine stays but all default is also gone.

Most likely bug 1437942.

From the console: TypeError: Services.search.originalDefaultEngine is null

I have managed to reproduce this issue using Firefox 62.0a1 buildID: 20180605220158.

The issue is verified as fixed using Firefox 62.0b7 buildID: 20180709172241 and Firefox 63.0a1 buildID: 20180711221812  on Windows 10 x64, Ubuntu 16.04 LTS and macOS 10.14. The default search engines are now correctly displayed and used for the zh-TW builds. The preferences section now correctly displays the search section.
