I believe the Sync feature requires a comprehensive review, primarily for two reasons:
Reliability issues: The Sync function is unreliable. Even when using the manual sync button, it often fails to synchronize properly.
Questionable necessity of manual sync: Most users prefer automatic synchronization. The existence of a manual sync button likely stems from the underlying reliability issues with Sync.
If reinstall Firefox on your device, Sync will have issues recognizing the same device twice.
While there is a page outlining how to report such bugs, unfortunately, Sync doesn't work, and my Firefox about:sync-log shows nothing (the log file does not exist).
In conclusion, I think there are numerous flaws in the Sync feature of the Firefox browser, particularly when setting up and using Sync in my Windows Desktop Firefox environment.
Therefore, I believe the overall Sync feature needs to be thoroughly re-examined and improved.
