  • (2022-05-27) Isabel Hobson: Really great, only sequential mass opener available - just won't allow me to check the box that will let me use it in incognito (have enabled it in the chrome settings to work on incog) but other than that works great! Could also be great to have a feature that automatically closes the tabs after they have fully loaded too!
