Hi dcoltrin, What is happening right before the crash? Also does this happen after updating Firefox and when temporarily disabling your antivirus? [https://support.mozilla.org/en-US/kb/update-mcafee-and-firewall-settings-allow-firefox-access Update McAfee and Firewall Settings to Allow Firefox Access] The signatures all have to do with socket streaming which are dedicated connections to sites for media. What website is this happening in? Have you scanned for malware? All these will tell us whats messing with the stream connection. Thank you!
