As suggested by jaykumar I created a new profile, restarted the computer, opened the University eResources site, the Foirefox does not open the list of Js did not solve Firefox crash nonresponse problem. Error message: The connection was interrupted The connection to libsta28.lib.cam.ac.uk:2416 was interrupted while the page was loading. The site could be temporarily unavailable or too busy.
