 * Remove the profile if the tests fail at the beginning for unknown reason.
 * If tests fail, isolate the one that causes problem, read debugging messages
 and keep your eyes on the browser window to understand its causes:
 a) In the tests, we often need to wait for a menu to appear ... If the 
 menu takes more time to appear than expected, the tests are going to fail.
 b) The websites change very often. And even if they are not changed, they some 
 time show a popup that broke the tests. In the case you need to login manually 
 to the website, close all popup and logout.
 * If you are logged in when the tests crashes, don't forget to log out before
 running the tests a second time.
