User Services/Sync/Debug Sync

Often it's helpful to provide diagnostic log data in bugs to help a developer fix an issue. Here are some tips:

Desktop

1. goto about:config
2. In the filter field type 'sync.log'
3. Context click on pref and set it as:
   • services.sync.log.appender.file.logOnSuccess to True
   • services.sync.log.logger.engine.bookmarks to Trace
4. In Firefox, go here: about:sync-log

You can also open the console to view errors: Tools > Web Developer > Web Console

How to force reauthentication

When you reset password this will cause all other devices to reauthenticate. To force that, edit this file:

<profile location [1] >/signedInUser.json

and delete some characters from the sessionToken value:

"sessionToken":"abcdef"

[1] On Mac:

~/Library/Application Support/Firefox/Profilesm/<some chars>.<my_test_profile>/signedInUser.json

adb setprop log.tag.FxAccounts VERBOSE

adb devices
