Ssl_error_rx_unknown_record_type

I keep getting this pop up box saying:
An error occurred during a connection to support.mozilla.org.
SSL received a record with an unknown content type.
(Error code: ssl_error_rx_unknown_record_type)

Is this the only website with the problem??
In case one of your extensions is involved, could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?
