I have problem with Firefox(31.0) on my Windows(7). I don't want that Firefox use system proxy, and for this issue, set "No proxy" in Options/Advanced/Network/Settings. But when I close Firefox then open it, this option changed to "Use system proxy".
I do this config in "about:config" manually.(set '0' in network.proxy.type) But similarly when Firefox restarted, this value changed to '5'.
How can i set permanent config for this ?
