Bugzilla

**Description**
All search engines are missing in  Staging using Firefox latest Nightly 79.0a1 (shows a blank list)  when using Dump enabled on bucket  "main-preview")

**Environments**
Windows 10
 
create user.js containing:
user_pref("services.settings.server", "https://settings.stage.mozaws.net/v1");
user_pref("security.content.signature.root_hash", "DB:74:CE:58:E4:F9:D0:9E:E0:42:36:BE:6C:C5:C4:F6:6A:E7:74:7D:C0:21:42:7A:03:BC:2F:57:0C:8B:9B:90");
user_pref("services.settings.load_dump", true);
user_pref("services.settings.default_bucket", "main-preview");
user_pref("browser.search.region", "US");
user_pref("browser.search.log", true);
user_pref("services.settings.loglevel", "debug");


tested with locales and all had the same problem:
en-US/US
RO/RO


**Steps**
Download latest USA localized Firefox nightly build.
Create a new profile and add the specified user.js in the profile folder before start-up.
Start-up Firefox.
Check list of the search engines that are installed by going into hamburger menu > Options > Search.
Check Browser console for errors.


**Actual Results**
No engines are shown. the list is blank


**Expected Result**
List should appear, like it does on The latest Firefox Beta 78.0b4


see screenshots attached.
