Avoid automatic connection
Hello,
I have some problems with the installation and execution of Firefox 52.7 ESR. First of all, I have an enviroment where the communication to Internet go throught a proxy and from the PC where is installed this browser only are allowed a few URLs.
I had installed a previous version of Mozilla 45 and I had no problem but when I uninstall the previous one and install the 52.7 version I find problem with a couple communications that seems to make the browser.
These outbound communication are:
redirector.gvt1.com:443 http://ciscobinary.openh264.org/openh264-win32-0410d336bb748149a4f560eb6108090f078254b1.zip
I have tried to avoid these communication by configuration in about:config but it didn't work.
Can anyone help me to avoid these communication? Does anyone know why the browser do it?
Thank you in advance.

Thank you for all your support jscher2000.
I didn't find a setting that let me avoid the connection to openh264.org so we finally decided to let this connection pass throught.
All the other connections, we achieved to avoid them at the end.
Thank you again.

While you are waiting for a response, I wanted to mention this support article, which you probably already have seen, but just in case: How to stop Firefox from making automatic connections.
The redirector.gvt1.com address might be for Widevine. See: Watch DRM content on Firefox.
Hello jscher2000,
first of all, thank you for you advice and sorry for the delay.
I've read the support article you mentioned, How to stop Firefox from making automatic connections. and that worked for some of the automatic connection but it doesn't work for the connection to http://ciscobinary.openh264.org/openh264-win32-0410d336bb748149a4f560eb6108090f078254b1.zip. How can avoid this connection? I even have this preferences "media.gmp-provider.enabled" to false and "media.gmp.gmpopenh264.provider.enable" to false as well.
I achieved to avoid the connection to redirector.gvt1.com changing a setting in about:config. I changed media.gmp-widevinecdm.enabled to false.
I think OpenH264 is used for WebRTC, so perhaps one of those preferences is relevant.
I thought that too, so I looked for settings in the config that let me change that but I didn't find a thing. I just found settings with the string "webrtc" related with logs or debug settings.
All the settings related with H264 are turning to false.
Oh, I think the relevant preferences have the word peerconnection in the name instead of WebRTC.
