Hi For years I successfully used the following two proxy.pacs on Windows XP Desk- and Laptops:

function FindProxyForURL(url, host) { 

  if (isInNet (myIpAddress(), "172.17.0.0","255.255.0.0")) 
     return "PROXY 172.17.4.10:3128";
  else 
     return "DIRECT";

}

or

function FindProxyForURL(url, host) { 

  if (isInNet (myIpAddress(), "172.17.20.0","255.255.255.0")) 
     return "PROXY 172.17.20.5:3128";
  else 
     if (isInNet (myIpAddress(), "172.17.0.0","255.255.0.0")) 
        return "PROXY 172.17.4.10:3128";
  else
     return "DIRECT";

}

..which did work well. Now surfing became extremely slow (about 20 seconds to see a site). When I fill in the IP address of the proxy in the config (instead of a proxy.pac) then firefox works fine again. It looks like the algorithm for interpreting proxy-pacs has changed; maybe for any new URL-connection the pac-file is re-interpreted?

Could somebody please help me?

Kind regards, Richard

Hello,

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

Hi 'smo'

Thank you for your fast response! Unfortunately it didn't change anything - and since the problem deals with the manner how the proxy is set I would have been surprised if add-ons would have caused the problem, but one never knows... Hopefully one of the developers can tell if there was a change how the proxy.pac-files are interpreted...
