3rd Party Page Redirect Warnings

I need to shut off this warning.

I do not get it for any other webpage in any other browser, so it is limited to the Ultimate Member plug-in.

The image is from Firefox but I’ve tested this across Edge and Chrome as well. The behavior is always limited to Ultimate Member.

How do I shut it off or in the very least, change the text in the message?

Please do not say its in the browser – I’ve tested other websites and they do not have this warning box, including testing other WP sites.

Thank you in advance – I appreciate the assistance.
