Saturday, when I tried to check my Discover credit card account online, it needed to send me a verification code via text. I entered the code and everything worked OK. I understand that, from time to time, this needs to happen for security purposes. The last text I got this message from Discover for this was back in February. But then, on Sunday, I got the same message. But this time, I never received the code. I waited about 10 minutes, then asked for a different code to be sent. I never got this one either. I called Discover, and they tried a few things & eventually verbally gave me a verification code. This worked and I logged in just fine. On Monday when I logged in, again I was told that they needed to sent me another verification code. I didn't have time to deal with it, so I moved on. Today, again it required a verification code. I didn't receive the text, waited 10-12 minutes or so, and requested a 2nd code. I never got this on either. I called Discover again, and was connected to their tech support people. We tried several options, then they suggested that I try using a different browser. I also have AVG on my computer. I tried that and got through to my Discover account instantly. They then suggested that I contact you to figure out what the problem is. After I got off the phone with them, I used AVG to log in and out of my Discover account maybe 5-6 times and never had any problem. Can you figure out why my Discover account isn't working with Firefox? I am currently using version 103.0.2. Firefox has been my primary web browser ever since I got my first computer in March 2000, and this was then known as Netscape Navigator 3.??? I have never had any issue like this with any website I have used until this problem started with Discover.com. THANKS!
