I often have open email tabs and come back to them days/weeks later to go through them. Today I was deleting emails not needed to free up some space, restarted the computer, and all my open tabs are blank, both the heading on the tab as well as the tab itself. I have no way to know what those emails were, except to go through a couple months of emails, looking for ones I had open. Any idea how to restore the text in the blank email tabs?
