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
