Sites using the popular Sencha ExtJS javascript framework (http://www.sencha.com/products/js/) don't work, since the ExtJS library fails to load. 
The ExtJS sample page (http://dev.sencha.com/deploy/dev/examples/) gives the following error in the inspector: "SyntaxError: Invalid regular expression: invalid range in character class". The Rally scrum tool (https://rally1.rallydev.com/) is another example of a failing site (the login button never appear due to the ExtJS error).
