User Reviews

Great lifesaver until they officially support the feature. Not sure if "Mirror" is NOT selected, will it duplicate groups or update them by adding new tabs? If I click "push", then sync the account on both devices, the other device does not show the new data even after several minutes wait. Bug 1: current version is loading the first tab of each group twice on first load. Bug 2: GUID ID appears instead of device name in drop-down menu on other devices. After a while on one device the name appeared. Not clear how it behaves. ___ Response to developer follow-up: Thank you for your response. I agree 100% with your decision on the cloud storage. I would just clarify the behavior to the users so they don't have surprises. Bug 2: I confirm they are synced now, so not a bug, but maybe inform users that it'll take a while. Bug 1: it might be that I synched twice, like you said, but I think it happened on the first sync, and actually clicking "mirror" later automatically deleted the duplicates, as expected. macOS with Firefox 151.0.2 (64-bit).

Is Tab Group Syncer Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Group Syncer requires a few sensitive permissions. Exercise caution before installing.
