Firefox Sync doesn't sync all settings

Just set the firefox sync up to sync firefox between my Win7-laptop and Win8-tablet, most of the firefox-settings* seem to sync and all of the extensions but none of the settings related to the extensions is present on the win8-tablet.

Is that how it should be? Reconfigure every extension installed (and to be installed)?

  • ) Not my pinned sites at the built-in New Tab-page or toolbar and firefox-menu however.

You can copy the related lines of prefs that belong to an extension from the prefs.js file on one computer to the prefs.js file on the other computer. You need to do this while Firefox is closed.

You can use this button to go to the currently used Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Only prefs that have a corresponding services.sync.prefs.sync.* pref that is set to true will be synced to other devices.

So you would have to create such a Boolean pref for each of the prefs that you want to sync to the other computer.

Thank you for the explanation, that seem logical.

Sadly however I was unable to get it to work when I tested it on one of the extensions. I added an entry in about.config (on both computers), but settings were not sync:ed.

Guess I have to settle for a manual config.
