I don't see a way to detect that a WPAD server should be used, and a quick look in my registry (HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\) doesn't reveal anything to me.Īccording to, the PAC-file (if there is one) can be found in HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections. That is, it will only use a static proxy (ProxyServer key) or a static PAC-file (AutoConfigURL key).
#Mozilla firefox internet explorer add on code#
The code in is not looking at the PAC-file that might have been found by the WPAD code.
I think I found it, but I don't think it will be easily fixed. All other traffic uses below proxies, in fail-over order. If IP address is internal or hostname resolves to internal IP, send direct. If URL has no dots in host name, send traffic direct. This is my PAC file, very simple as you can see : My DNS suffix is ".local" which I thought my cause issues if firefox was blacklisting anything that is not a sub-domain (cf ) however in this case forcing the auto detection would not work either, would it ? However this is not the default setting and I cannot enforce it on my network (roaming users, guest laptops, etc.). I don't think there is an error in my wpad setup as IE and Chrome work fine and Firefox too if i set it to auto-discover the proxy settings. Restart firefox and test whether a proxy is in use.įirefox should try auto-discovering the proxy settings using wpad. Set firefox to use system proxy settings (default in newer versions)Ĥ. In Internet explorer, set the proxy settings to auto-detect (do not provide actual values, do not specify the script's url, only check "Automatically detect settings" - this is the default in Vista / 7)ģ. Set up a working WPAD environment (I used both DHCP and DNS)Ģ. Firefox's default setting on Windows, "Use system proxy settings" does not seem to understand that it needs to perform auto-detection if Internet Explorer is set to "Automatically detect settings".ġ. Trying to setup automatic proxy discovery through WPAD. These browsers appear to only require the initial SSL Server Certificate and the Root Certificate Authority Certificate.User-Agent: Mozilla/5.0 (Windows NT 6.1 WOW64 rv:2.0b8) Gecko/20100101 Firefox/4.0b8īuild Identifier: Mozilla/5.0 (Windows NT 6.1 WOW64 rv:2.0b8) Gecko/20100101 Firefox/4.0b8 Google Chrome and Microsoft Internet Explorer appear to not require the Intermediate Certificates in the SSL Chain. The missing Intermediate Certificates may be the RSA Domain Validation Secure Server Certificate and the RSA Certification Authority Certificate. There are numerous reasons for encountering the message: "This connection is untrusted." However, you may find the issue is due to missing Intermediate Certificates in the SSL Chain. I had to resolve the issue by deleting the certificate entirely both CRT and Activation and then re-installing the Certificate using the CA-Bundle from the Certificate Authority. I encountered an issue where the SSL Chain was broken and it was only Firefox that displayed the Untrusted Connection warning but it was only if Firefox had not previously cached the Intermediate Certificates from another website. If you can also point me to technical documentation from Microsoft and/or Google that confirms this that would help as well. I don't see technical documentation regarding this issue so your help is appreciated. It may have something to do with the caching of certificates or it may be as I have described below. I am attempting to document why Firefox displays a warning while Chrome and Internet Explorer do not.
Can someone please confirm the following for me? Or make any corrections? I want the information that I document to be completely accurate.
