I am not sure what this feature is called, but it's not working properly

So…I have been using Bitwarden for a few years and I signed up for premium service, because I want it to survive. I have a login page for my router where the fill in feature used to pop up at the password box, like this one:

Recently, that box doesn’t pop up in the password box. I can select the extension on the toolbar, select the correct item and have it fill in the box. After a few days, the correct selection would still appear (see screenshot), But would produce an error that it couldn’t fill in the password.

I uninstalled the extension and re-installed it. It still doesn’t want to fill in at the password box, but I can select it from the extension and have it fill the box.

Nothing changed for the router, but I don’t know if something changed in Firefox or the extension. Can anyone tell me what has caused this and how to fix it?

Firefox 129.0.2 (64-bit), Bitwarden Version: 2024.8.1 Server version 2024.8.0

Thanks.
