But i found a way to disable it. :3
*note, i only did this in firefox, sorry other browsers*

~go to the url or (location bar or browser) and type in about:config
~~in the filter search type in backspace
You should have an item called browser.backspace_action
~~~change the value of it from 0 to 1
~~~~you won't accidentally backspace out of the game anymore.
*note* You can still use back space to delete your messages and what not, this just disables it from going back to the last page you visited in the window.*
