I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

When I click to fill in a Credit Card field to pay for something, my correct card info appears momentarily, but then disappears. To execute a payment, I am forced to manually fill in all required information. I made sure the "save autofill" box was properly checked in the Settings, and it was. Names, addressed, etc. are all filled in properly; only credit card info is not.

Settings->Passwords and autofill->Manage payment methods Only gives me the option to "Add new payment method". I can fill that out, but cannot save it.

I have an old credit card saved that I cannot update, change, or get rid of. That number was replaced with a new one, so it's not even valid anymore.

I followed the recommendation under the help file to check "Privacy and security->History", and it's set to "Remember history", so that shouldn't be a problem.

I was having this problem on my previous Windows 10 laptop - after transferring everything to the new one that's running Arch Linux, it's still the same. I'd really like to fix it, thanks.

I use Firefox for Linux on a Lenovo ideacentre desk top and on an Android mobile (Google Pixel). I live in the UK. I've saved my debit card details on both devices and autofill works perfectly on my phone but won't work on the PC. I've checked settings multiple times and everything seems to be properly set. I've just checked (via about:config) that my regions supports autofill and it does. When I try to use autofill, my card details appear in a box but when I click on the card number to fill the details, nothing happens! I've tried disabling the extensions I normally use on the desk top (Privacy Badger and ClearURLs) but that didn't resolve the problem. Any help would be appreciated.

When a site asks for my address, I try to choose one from the drop-down menu of addresses offered, but it firstly prints my address in the address window and then, when I press enter or do anything whatever, it deletes everything in the address window. Worse than that, if I try to ignore the dropdown list offered, and try to type in my own address, it deletes it.

This behaviour continues, no matter what I try to do do trick it into either (a) filling in my address, or (b) using the offered addresses in the drop-down menu. I.e. there is nothing I can do to ever get an address to stay in the address window and give me a fully filled out form - the address window always ends up empty.

I've tried to alter the settings, telling it to ignore the automatic filling in and remembering of addresses, but I can't turn this address-killer feature off.

Yes, it's made filling in forms on line impossible, since it keeps making the address-window empty

At some point, I told firefox my credit card details, and enabled supplying them to websites on (my) request.

This has stopped working, It offers the correct credit card (at least the correct final digits) but does nothing when I click on it.

A previous article suggested that going into settings and editing the credit card might fix this, presumably because this undoes some corruption previously introduced by firefox code.

I tried this and found that clicking on "edit" is also a no-op.

-- I'm running Firefox 150.0.3 (64-bit), installed as a "snap', on kubuntu 26.04 LTS

My installed extensions are OneTab, Proton Pass, and uBlock Origin.

Firefox has been repeatedly auto-upgraded - approximately every two weeks - until I got sick of the churn and researched how to stop it.

The OS has been updated to a new version, once, and had various bits and pieces upgraded repeatedly.

It's likely that I supplied the credit card while still on the versions installed with this system, so there's been time for repeated upgrades to break something.

I do not log into firefox, i.e. I don't share this firefox config. with any other firefox installations.
