Eno was working just fine in my Firefox browser since installing it a couple years ago, then recently it began to consistently malfunction. Since about May 2020, clicking the Eno icon brings up a "clueless Eno" that can't determine it's already been installed--despite the 20 or so preexisting virtual card numbers on file (which couldn't have been created without Eno being installed.) Stoopid Eno!

During the 1 hour, 50 minutes, and 53 seconds spent on the phone with Capital One Customer Service, the truth came out. The June 5th, 2020 implementation of the current Eno version was tailored to work just on ONE of today's top 5 web browsers--NOT Mozilla Firefox, NOT Apple Safari, NOT Microsoft Edge, and NOT Opera. Eno now works properly on ONLY one web browser, Google Chrome.

Once again, Capital One, thanks for less than nothing!
