All my home computers and my friends are getting SSL_ERROR_RX_RECORD_TOO_LONG with the latest firefox update .
So yeah i was talking with a friend and we both got a firefox update at the same time , as soon as the update finished installing , we started having this error on half of the websites we visit , sometime refreshing the page works sometimes it just does nothing .
That issue seems to be happening only with firefox , opera and chrome both works perfectly .
Additional System Details

thanks for reporting the problem, so far we have heard about this from avast/avg users whose security software is meddling with encrypted connections. firefox 61 introduced the better security protocol tls 1.3 & apparently avast can't cope with that yet.
as a workaround, please try to disable the scanning of https connections as described in https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message#w_avast-and-avg-security-products
