Users appreciate About Sync for its ability to reset sync history quickly and restore synced tabs, making it easier to manage sync issues across browsers, including private sync servers.

Cons

Not user-friendly, appears designed more for developers
Lacks an option to report sync failures directly to Mozilla
No support for Firefox for Android

2025-12-08	Al*****	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.

2023-09-18	Im*****	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.
