1. No, Pale Moon is not considered a “major” browser. If it does not show up in the list it is not included.
  2. Browser Integration does not include the autosandbox found in the free version. Pro, AIS and Premier have the on-demand sandbox.
    The autosandbox is in the file shield and not the web shield.

There is absolutely no reason to be rude. Rudeness is totally uncalled for and will not be tolerated.
