hello, please update to firefox 43.0.4 which will likely solve this problem for the moment. this is likely caused by your security software (avast?) intercepting secure connections.

There are other things that need attention. Your System Details List shows multiple Flash plugins.
- Shockwave Flash 19.0 r0
- Shockwave Flash 20.0 r0
You can find the installation path of all plugins on the about:plugins page.
You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.
