Every time I use Firefox, at some point (and sometimes multiple) I get the message "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Script error chrome://global/content/bindings/browser.xml:244 This is of course accompanied by my browser slowing down significantly. I am running Firefox 35.0.1 on windows 7. I do not have chrome installed. I do not have any add-ons. I do have some plugins but everything google-related is on "ask to activate". What is causing this and how do I stop it?
