Tab Group Syncer par Sudhir Babu Nakka

I love the new tabs grouping feature that my beloved firefox introduced but have been missing the groups not being synced across devices. I wanted and needed this for my personal workflows to be efficient. Hence had to develop this plugin.

It is now opensource - https://github.com/sudhir-asuracore/firefox-tab-group-sync

If you wanted this and/or think this helps you - consider supporting it (The funds are forwarded to a walking stick for blind donation target I have)

I will maintain it until firefox officially introduces tab group sync.

Once installed, you can provide a name for your current device. This will show up on your other devices during sync.
Click on the plugin icon - you will see a popup where
* you can provide a name for your device
* you will see a list of your devices and any tab groups available from that device
* select/deselect tab groups you want to be pulled/synced and trigger a sync

The plugin uses firefox official sync service and storage - so it is extremely secure and the data will be in firefox control as it is with existing sync.

Note: Firefox sync is not a real time sync and can have a minute or so delay.

Plugin is open source under MIT license. Feel free to play with it, contribute to it or make a version of your own.
