Firefox not saving manual proxy configuration
Sometimes we may face an issue like re-setting proxy configuration whenever we restart/open a firefox.
In that case other than reinstalling firefox, follow the steps to fix that issue.
* First check whether the following line is present in pres.js("D://Documents and Settings//CurrentUser//Application Data//Mozilla//Firefox//Profiles//.default"),
* If you find the line, set the value for PROXY_IP_ADDRESS and PROXY_PORT manually.
* If it is not present, add those lines at the bottom of the file with your "PROXY_IP_ADDRESS" and "PROXY_PORT".
* Save and close the file.
* Now restart firefox.
Now it will save the proxy configuration setting.
