Awesome! Thank you!😃
My main use for this extension is to save all open tabs from my phone. I copy them as a JSON string and paste them into SyncedJSONtoOnetab
If you're interested, you can find the SyncedJSONtoOnetab repository and use it to save tabs in Onetab format.

Unique and useful👍🏻

Excellent idea, thank you for creating this add-on. My main use for this is that I would like to sync additional FF settings between browsers and this should help with identifying any issues.

saved my day, got my synced tabs back

Very helpful for resetting history so that it can start syncing again. Hope it could work for Firefox for Android anyway.

very useful, because can reset history sync with a click on a button

When a sync fails, I'd love to be able to report the failure to Mozilla so they can look into it!

Super pratique !
Surtout pour vérifier que son sync server privée fonctionne bien

Made for developers, not user friendly.
