I kept getting this error whenever I opened Gmail in Firefox: "You are currently viewing Gmail in basic HTML. Switch to standard view". I would click on the link, but it would return to the same page. It would make sense if my browser couldn't handle Gmail, but I had been using Gmail in Firefox for months. So I searched online and found this solution: Goto http://gmail.google.com/gmail?nocheckbrowser. The "nocheckbrowser" option assumes that your browser can handle everything.
I also used to get some sort of error about a problem connecting to the server. It would pop up an alert box. I looked around and read something about using Gmail's secure server, so I checked it out. I haven't had the problem since. [[technology]]
