Code Issues Proposed changes

Fix back button on Firefox and Safari 

Firefox (and Safari) uses bfcache (back-forward cache)
to load re-visited pages. The solution is to force a reload
when page is loaded from bfcache, so back button will work
correctly.
More information can be found here [1] and here [2].
