Same symptom.

This is the general/general tab. Please be more specific if necessary.

Every website set to use Firefox has same result, irrespective of http/https. If I only change browser to IE, Edge or Chrome they all function normally. Pages load correctly in external Firefox browser, just not in RDM.

Running RDM version 12.5.6.0 x64. Firefox version 54.0.1 x64. Firefox extension 5.1.1.0 installed per instructions.

Issue is web connection seldom if ever load in RDM, just get a blank screen with green spinning circle in the corner. On the rare occasion it does load, it only loads some of the page and hangs.
