Actual results: The page loaded with part of it blank in the middle. Expected results: Extra content should have been displayed in the middle.
Found it's caused by the add-on, HTTPS-Everywhere: https://www.eff.org/https-everywhere.
I've been able to reproduce this bug and confirmed that it is fixed by disabling the Apple.com rule in HTTPS Everywhere. Please open a ruleset bug at https://github.com/EFForg/https-everywhere/issues.
Is this still an issue? The only apple rule change i see is https://github.com/EFForg/https-everywhere/commit/b80007e4ea490a8d5d673fb816d124fd8a61e8f6#diff-6594837f75e34da15f18794199770151 since this report get filed.
