Is Tab Mover safe?

Clean risk

Move tabs between Firefox windows from the context menu.

This extension adds context menu options for quickly moving tabs between windows. It supports moving tabs between normal windows, between private windows, and from a normal window to a private window. For tabs in a private window, it can optionally close the tab and reopen its URL in a normal window because direct moving is not possible.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
