unable to login to dashboard via external browser

[Mylilpwny]

As of a few days ago i cannot log into my dashboard or complete transactions on MP via my external browser. Both places just go blank. But i am able to log into dashboard and also make purchases on MP if i use my built in on the viewer. I prefer to use external since it is less laggy. Any ideas on how to fix this issue?
