Yes, tried rebooting. I don't think one page fully loaded whereas before most fully loaded. Tested things like the BBC, CBC, Github, Bitbucket and here.
Guess I should revisit trying to build NSS, it is weird as it uses the NSPR4 build system but it sure reminds me of how the Mozilla apps vanished (no where as much though) when using the latest system NSPR4/NSS.
