Diễn đàn hỗ trợ Firefox

Am trying to update my email address. When I try to make the secondary the primary, it wants a verification code entered. The field for this code will not let me paste it or enter it manually. Will this glitch be fixed soon?

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.
