This is more of a heads-up rather than a ques tion. I recently update Firefox to version 35. My computer operating system is Windows 7 Starter. Since adding the update every page I pull up I get a Java script error message "Error: 'console' getter called on an object that does not implement window interface." I followed the steps for trouble shooting extensions and managed to isolate the problem. It was an add-on extension for Youtube Auto HD 1.4. The message no longer pops up. I hope others out there find this helpful.
