My problem is a hijack of the proxy settings and I cannot remove it even by editing pref.js file. It just keeps restoring the use manual proxy settings.
I had the cycbot trojan and have removed it. However my browser will not connect to the Internet unless I manually select no proxy in the connection settings. then on restart of firefox the settings change back to a manual proxy.

I think what you can do here is to go to about:config and then in the filter at the top, enter each of those entries one at a time, then right click them and choose Reset. This should restore their default values.
So network.proxy.http_port should revert to '0' when you do that instead of its current value of 64586.

I looked for files modified at the time I thought a similar Malware acted on my PC.
Found 3 lines added to the:
C:/users/xxxxxmyprofile/appdata/roaming/mozilla/firefox/profiles/xxxxx.default/extensionsfoxmarks@kei.com/default/preferences/prefs.js
I removed them, and I saved the prefs.js file again. They were like: user_pref("network.proxy.http", "127.0.0.1"); user_pref("network.proxy.http_port", 58505); user_pref("network.proxy.type", 1); More or less.
My suggestions: Check all *.js files in firefox/ subfolders, plugins included (in my case, as you can see, it was in foxmarks subfolder).
Took me a while, finally solved.
