1574731 - firefox sync not restoring many preferences

Status: RESOLVED DUPLICATE of bug 1269548

(Firefox :: Sync, defect)

Description

[Brad R]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

• Delete and recreate firefox sync account.
• Delete $HOME/Library/Application Support/Firefox folder
• Start firefox (so it is in fresh, default state)
• In about:preferences, log browser in to Firefox Sync
• Disable telemetry, change default search engine from Google to Duckduckgo
• Confirm that sync has completed (about:config lastSync)
• Quit Firefox
• Delete $HOME/Library/Application Support/Firefox folder
• Start Firefox
• Log in to Firefox Sync
• Wait for sync to complete

Actual results:

The "default search engine" is still on Google.
The telemetry settings are enabled.

Expected results:

My synced preference changes should have been applied:

• The "default search engine" should have been restored to Duckduckgo.
• The telemetry should have been disabled.

Other settings that do not restore from sync (similar to the two examples above):

• my network proxy settings
• my cookie "Manage Permissions" settings

Many preferences are being restored (so some sync functionality is working), for example:

• bookmarks
• browser.contentblocking.strategy

Notes:
MacOS 10.14.6
Firefox 68.0.2 (no extensions, virgin install)

Thanks for the report - we are tracking the things we should sync but currently don't in bug 1269548, so I'll resolve this as a dupe of that.
