psreloaded Posted May 14, 2012 Share Posted May 14, 2012 Look in IE to get your proxy server certificate. Mostly it will be with your company's name. Export it and import it in Firefox. Once that is done edit the trust settings for the certificate to allow it to identify websites. I think its in the authorities tab in options for Firefox. You should be good to go after this... Hope it helps. The reason this happens is because organizations sometimes want see and track activities on secure sites of their associates if they want to. They bypass the original certificate and put their own. Link to comment Share on other sites More sharing options...

g0dzilla Posted May 15, 2012 Share Posted May 15, 2012 Are you using a PAC (Proxy Auto-Config) file for Internet access? I'm guessing that this works for other browsers like Google Chrome and IE... I had a similar situation at work whereby the PAC file would not provide Internet access in Firefox, but setting the proxy to the manual IP address worked. Ideally we wanted the PAC file to work in all browsers, so this was the fix: IPv6 Firefox supports IPv6 by default, which may cause connection problems on certain systems. To disable IPv6 in Firefox: 1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page. 2. In the Search field, type network.dns.disableIPv6. 3. In the list of preferences, double-click network.dns.disableIPv6 to set its value to true. 4. Close and restart Firefox to test. Hopefully this solves your issue!

CPressland Posted May 15, 2012 Share Posted May 15, 2012 If this is a corporate connection - why not simply ask IT? Link to comment Share on other sites More sharing options...
g0dzilla Posted May 15, 2012 Share Posted May 15, 2012 I'm assuming it is as the OP mentioned that he "checked with Admin"... Link to comment Share on other sites More sharing options...
g0dzilla Posted May 15, 2012 Share Posted May 15, 2012 Also check here to see if SSL is enabled in Firefox: http://support.mozilla.org/en-US/kb/Firefox%20cannot%20connect%20securely%20because%20the%20SSL%20protocol%20is%20disabled There is a link at the bottom of the webpage above to test SSL connections in Firefox; see below: http://weblogin.bu.edu/troubleshooting?cmd=ssl Do you have SSL connections configured to go out via your proxy in Firefox also? > http://superuser.com/questions/254481/unable-to-open-any-https-site-using-firefox Link to comment Share on other sites More sharing options...
psreloaded Posted May 15, 2012 Share Posted May 15, 2012 exported but when tried to import didnt import any other solutions ? can restore defaults help See if the admin guys are ready to provide the certificate. Try importing that to Firefox and editing the trust. Link to comment Share on other sites More sharing options...
g0dzilla Posted May 15, 2012 Share Posted May 15, 2012 This website seems to have a lot of good information on this issue, but you didn't mention any errors being reported; if any: http://kb.mozillazine.org/SSL_is_disabled Link to comment Share on other sites More sharing options...
