Added a tab to it, and when I opened, it replaced all my other tabs. Had to uninstall

Not so good. It works fine, until all tabs and groups disappear. This happened to me twice, basta, I uninstall and only one star. Avoid if you REALLY care about your open tabs...

0.18.25 . Not functional. Shows a single group, not what is in it. No button to add another group.

Unfortunately, in Windows 10\Settings\High Contrast the extension settings page is all black, impossible to read
