Running: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b4pre) Gecko/20100816 Minefield/4.0b4pre http://alexa.com/ is not loading or redirecting to www.alexa.com http://www.alexa.com/ loads just fine Looks like Minefield is not auto filling the www part of the URL.
Gecko should never automatically change the subdomain on it's own. The change from http://alexa.com/ to http://www.alexa.com/ is done by the page with a 301 and that works for me in my SM trunk build. Do you already tried http://support.mozilla.com/en-US/kb/Safe+Mode ?
Thanks Matthias! Looks like Add Block Plus is the culprit. It was broken for a time on Minefield and not enabled. It looks like the new revs have the Add-on enabled and it's causing the behavior I'm seeing. Does this go to Tech Evang?
No, this makes this report invalid You should notify the extension authors if you find a problem with their extension.
Looks like there is a forum thread on this one in the ABP world. Thanks.
