Can not log into Cox email.

Sorry you're getting the runaround.  You're absolutely welcome to forward this thread to the folks at Cox.

If they need to have an engineering level conversation to understand what's going on, we'd be more than happy to help.

They can send me a private message (just click my username) with contact information, and I'll get something going.

In all likelihood, this is simply a support training issue, and there's some work on their backlog already to move away from Flash-based login on their email system (which is ultimately what needs to happen, and in short order).

I had the same experience.  COX email told me to contact ADOBE, it was Adobe's I/T problem, something went wrong with

the update.  Totally refused to even assist me......I need my email for my business invoices....very disappointed and inconvenienced!

Also, you should definitely complain to Cox about the user experience.  There are changes they could make on their end to improve this, including moving to an HTML and JavaScript solution for login.

This is a browser issue, not Flash Player issue.  Major browser vendors block Flash by default, forcing users to enable it, usually per-site basis.  See https://helpx.adobe.com/flash-player.html for links to enable Flash in the various browsers.

Note, that as of Chrome 69, the Flash Player settings only (e.g. allow/block Flash) remain ONLY for the duration of that session.  Once the browser is closed, the settings are removed.

Refer to Google's Flash roadmap here, Flash Roadmap - The Chromium Projects , specifically section 2.2:

Summary

Sites using Flash will require explicit permission to run, every time the user restarts the browser.

Rationale

Require affirmative user choice to run Flash Player content, without that choice persisting across multiple sessions.
