I tried to switch to Firefox, but I fill out a lot of forms, and it doesn't have autofill for them. It makes it very slow and frustrating. I've searched for solutions to activate it, add ons for it, etc to no avail. It seems that function may only be available in the US? It's strange to have such a basic feature missing.
I basically switch to firefox until something I need doesn't work, then I go back to chrome until they do something scummy. I'm back on firefox now and the experience is better than previously. I will probably stay and keep Chrome for "just in case" stuff or when I want a browser with no privacy/adblock extensions.
Firefox cannot autofill forms outside login credentials last i knew. That's not a feature in it. So details like addresses and credit card info are not auto filled.
