I used to sign in to GMAIL with no problems - email, password, done. Now I am always told that "This device is not recognized" and that Google wants to verify that it's me. So I type in the recovery email address, and I'm in. This started within the past week or two. I'm at a loss to figure out what changed, and I'd like to avoid having to type in the extra email address. This does not happen when I use the EDGE browser, only when I use Firefox, which is why I'm directing my question to Mozilla support. I tried playing around with the settings on Google, but the problem persists. Any suggestions?
