Firefox Community Forum

Social Security just stopped me from downloading my 2026 COLA on Firefox with an error 400 (bad request), but I was able to do it on Edge. More and more websites, particularly financial and government websites, work with Edge but not Firefox. And when I call their customer services, their first response is "try another browser!" Why do they hate Firefox?

If someone wants me to walk them through an example of the problem(s), I can do that when I pull statements or pay bills on those websites. The worst example is Synchrony Bank, which runs several credit cards I use. You may contact me by email at [email removed]@att.net (put FIREFOX PROBLEM in the title so I don't miss it).

I also have Mozilla VPN, and some things only work when I turn off the VPN, so that may be compounding the incompatibility. Although I am in Eugene (OR), the closest location for my VPN is Seattle.

I am not able to receive mail from a user sending me mail from a gmail.com account. I have communicated with my ISP Optonline.net and they state the there mail process "checks out" and the issue could be the browser I am using, Firefox. The last email I have from a gmail.com sender was 8/28/2025. I have asked two different gmail users the send me mail and have not received any of them. I have cleared the Firefox cache but that did not correct the issue. I come to you to figure this issue out and hopefully solve it.
