why is it that I cannot sign in facebook with my gmail address 'sarpkag.1970@gmail.com

I have not received any answer to my question

Hi Frank, These forums are run by volunteers, normal people like you and me. That might be why your query hasn’t been answered within two minutes. 🙂

Just to make sure, you are able to log into your Facebook account using a different browser? And for our reference, could you state the version of Firefox you’re using?

Thank you in advance for making your query quite a bit less of a wild goose chase that way. Kind regards, Dick
