I few minutes ago, I was signed in to my google email and other accounts and needed to log out. Now, when I try to re-sign-in, I can no longer access the google/gmail sign in page, I get directed to the "Clear cache" page. I've cleared my cache and cookies a number of times, restarted the computer and firefox (my firefox is up to date). I contacted google; they say the issue is with firefox. Everything was working fine an hour ago, but now I'm shut out? I can access the sign in page if I open the page in a "private" browser window. Anyone else having this issue? Any help?
