Open firefox, open Gmail and a box with, TypeError messagebox[0] is unidentified, opens. Have to click x to shut and a second box that opens. This happens every time opening Gmail.

Don't know about the messagebox[0] error but it could possibly be related to the following problem which has come up several times today. Can you actually see your emails in your inbox, or have you just been writing emails so far today. Try Googling the exact message and paste it here before solving to help others later find solutions based on exact message wording when you or someone else does solve problem.

GMail entire message content missing (blank) after header title

In Firefox, if you have "Adblock Plus" extension.

  1. "Ctrl+Shift+F" Preferences (or right click on ADP symbol, and choose preferences)
  2. 'Filters' menu > "Update all subscriptions"
