I use Firefox on my iPhone 12. When using commercial websites where I need to be logged in, such as for example a retailer where I have a loyalty account, I am constantly logged out and need to log in again. When I do log in, it at first appears to auto-fill my credentials but then when I try to proceed it throws an error and I have to type them in by hand. This happens across sooooo many different websites that I'm convinced it's the browser and not the site. It's driving me so crazy that I am planning to switch to another browser. Before I do, is anyone familiar with this issue? Does anyone know how to solve it?
