I am using on Firefox nightly. I cant see why there would be a problem on beta.

Please post the details to the support page so that we can fix it.

Hello

Thank you. I will add it for the next update. The location for translations are here: https://github.com/erosman/extension-translations

The new Quantum API does not allow saving anything to the computer (outside extension storage). The only available method is to use the Download API. The Download API can only use the location save for download in Firefox Option.
For further discussion, you can post the requests to the support section.

If you disable the Tab IP, both IP & flag will be disabled.

Context Menu

Enable or Disable each item on the context-menu and/or re-order the items. Moving the main menu will move its sub-menus.

Disabling the Tab IP also disables its process and listeners as well as Country Flag Display of host location (v2.10) (IPv4 at the moment).
