Why is it more secure to quit your browser after you have logged out?

[Tom]

When you log out from Tapestry no one will be able to add or edit an observation, or access anything you haven't recently had open.

 

However, if you have accidentally left other tabs open that show the contents of a Tapestry page then people can still switch to those tabs and see what was on screen.

 

Furthermore, on some browsers, in some situations, people can use the back button to see some of the information that you were recently looking at.

 

The best way to prevent those two possibilities is to quit your browser after you have logged out.
