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
5. You should see Success and Error logs. You can click to open, often you will want to upload this to your bug.

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

"sessionToken":"abcdef"

[1] Profile locations

Windows XP / 2000 / Vista / 7 	%AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\signedInUser.json
Linux 	~/.mozilla/firefox/xxxxxxxx.default/signedInUser.json
