Firefox Community Forum

Hi,

I've noticed that Firefox is no longer performing all the functions of some website. For example, when I use the Kaiser payment website, everything works until I enter my payment info. When I use the CA DMV app, it stops working after I enter the my username, password, and security code. In all cases, the website returns to the Login or Enter-Data screen. There are no error codes, just an endless loop of attempts to login or pay.

Firefox used to work on all of these websites. This error started happening on the prior-to-last update - currently on 135.0. It started happening before I updated my MacBook Pro to Sequoia 15.3. Still, the same thing happens on my Windows 10 HP laptop at work.

I am able to get full functionality on these websites when I use the Chrome browser. But, I like Firefox's functionality and security better! :-(

I have two mac computers with the same version of Firefox. (135.0) Autofill stopped working on both of them and they are not synced to each other. What to do to get autofill working again?

Thank you, Martha

This is an exact copy of a question with the same title by Steve Ediger, of August 2022, now archived.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, the details appear on the form but get removed almost instantly.

I am in UK. It was working until recently.

None of the earlier answers have helped.
