In my Firefox email when I click on an email it opens to the entire page, but then if I want to get back to see the "Inbox" with the accounts and various folders I have created it seems the only way to do it is to scroll back on the line at the top which sometimes is short but literally sometimes takes a very long time and I don't know how close I'm getting, or I have to go up and click on the little contents box in the upper left corner, click on something else, like calendar or tasks to get out of email and then click on the contents box again and click on email. There has to be an easier way???

Thanks for any help in advance.
