Locking of Preferences disables Update to a newer Version

locking the firefox proxy settings using this method ( works for me just fine. The Problem arises when I try to update to a newer Version of Firefox (specifically 39.0 -> 39.0.3) which results in a error, before the update is downloaded, saying "Update failed" ("Update fehlgeschlagen").

Is this a known problem and is there any fix?

The two files look like this:

// lockPref("network.proxy.type", 1); lockPref("network.proxy.http", ""); lockPref("network.proxy.http_port", 9999); lockPref("network.proxy.no_proxies_on", "localhost,, .x, .y .z");

pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg");

hello, this will depend on what your proxy is doing with the network traffic...

Looks like you are correct. I just configured the proxy manually and the problem still exists.. What was strange is that on one pc it helped to delete the custom config files but on another one it didn't matter..

is the proxy somehow man-in-the-middle'ing secure connections? i think there are some internal checks in firefox that should assure that the connection to the update server is not tampered with...

Possibly, I can't tell you for sure..

Is there a way to lock preferences only for a specific profile and not globally like it is right now? That would at least be a workaround to the problem for me.
