Unfortunately, it cannot get through the corporate proxy server which expects the entry of domain\user and password. FF 1,07 has no problem prompting for this. In fact, even IE 6.0 does this. Reproducible: Always Steps to Reproduce: 1. Start browser 2. enter a web address other than a local address 3. browser fails to get thru proxy server without prompting for domain\user and password Actual Results: It's not really that complicated. See above. NOTE: connection settings for 1.5 are identical to those from 1.07 which works. Expected Results: Should prompt for domain\user and password as 1.07 and previous versions did. Maybe it's something I'm doing or not doing. But I can't see it. I've even reinstalled completely from scratch. No such luck. It does not seem to know that it needs to prompt for access info and I can't see where one would enter this - as some other ptoggies have. It is labelled as security only because proxy access is security related (see below - no checked) A major feature (the browser itself) may be broken.
might be a dup of 318253 .
Is this still an issue ?
Actually it happen on all platforms. With Google Chrome not happen it and like Firefox user I suggest that does  but now the solution is broken and nobody can surf. Or happen NTLM Proxy authentification dialog pops up over and over.  http://firefoxmania.uci.cu/firefox-me-pide-contrasena-muchas-veces-que-hago/
