Just to clarify what I said a little bit, the cause of the issue seems to be that in the recent dev chrome builds, extension windows no longer define window.url (previously, window.url was a chrome:// URL). A bunch of adblock plus code seems to assume that window.url is defined. The function that crashed in this case was isFrameWhitelisted, but there may be more places in the code where undefined window.url might need to be handled.
