With M15, if you have manually assigned proxy entries you correctly get prompted to authenticate with the proxy. With both M16 and the nightly build grabbed on the 28/June/2000, you do not get prompted and it just fails to load the desired page. ( as expected with proxy auth. failure ) I have to submit this bug from within Netscape as Mozilla wont get beyond my firewall. This is THE most important bug from my point of view as with getting beyond my proxy I can't assist with very much. If you need any further clarification of what the problem is feel free to email me for more details.
