Ubuntu – Reset firefox from command line

Firefox just can't do the standard thing and use environment variables (though to be honest this is partly justified as the standard thing doesn't allow for proxy autoconfiguration files). The preferences for static proxies are

user_pref("network.proxy.http", "wwwproxy.example.com");
user_pref("network.proxy.http_port", 3128);
user_pref("network.proxy.type", 1);

There's a Firefox extension to use $http_proxy and similar environment variables: Environment Proxy.

Recent versions of Firefox supposedly use the usual environment variables by default, or if the proxy type preference is explicitly set to 5 (“Use system proxy settings”), but it doesn't work for me with the version in Ubuntu 10.04.

user_pref("network.proxy.type", 5);

Thanks for the reply, As it happens over the last 24hr i have tracked down why this was not working.

I tested the same c ommand on Suse, Debian 6 and fedora, and it worked fine on all of them which i found a bit strange, however once i updated Ubuntu 10.04 it worked. so i checked what the last updated had supplied, and it seems the recent OpenSSL update has resolved this issue.

To confirm this, once back in the office i installed the same open SSL update, and it all worked fine.

As a final check i tried this on a fresh Ubuntu 10.04.1 install, it failes, run updates it works..

to be very specific. the pk12 command

pk12util -d /home/df001/.mozilla/firefox/qe5y5lht.tc.default/ -i client.p12

works
