My link also tells you in big bold letters that EZ-RC only works in IE, period. No way around that. What operating system are you running? There are over a billion computers running Windows. You need access to one of them for 5 minutes, long enough for your remote to update to the latest firmware. Then you never have to use IE or EZ-RC again.

You can use Remote Master instead right now, also found at my link. But it won't work 100% until you've made at least one connection to EZ-RC in IE. If you use Remote Master on a remote running an old firmware, you can do everything except turn off the Assistant screen on the remote. With the latest firmware, you can do everything in Remote Master.

Those are your only options.

If you are getting some credit card scam pop-ups, you have far bigger problems with your system.
