I have a very strange problem. Every time I try to login to Gmail (https://mail.google.com/) with my username and my password over a browser (Firefox, Chrome & Internet Explorer), I cannot login. It says: "Username or Password incorrect".
If I try to do the same with an Android based browser (on mobile phone and Kindle Fire) the login works just fine.
I replicated the problem on four different computers with Linux (Mint Xcfe), Windows Vista& Windows 7) over the course of a week.
It just drives me crazy. Did anyone have the same problem? Or found a solution?
Thanks very much in advance!
