I'm using Ubuntu 12.10 it's fully updated. Java & latest Flash Player that Adobe released is installed, and I'm using the nightly build of Mozilla Firefox 22.0a1. My country Filters Websites like facebook.com and youtube.com , but my problem isn't that. I can open youtube in HTTPS [video streaming won't function due to filtering] but at least i can search the youtube. but when i use https in firefox it gives me :
Secure Connection Failed An error occurred during a connection to youtube.com. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.
my plugins and extensions are[which i believe don't have anything to do with my problem] : Omnibar, Firebug, Ghostery, DNT+, Adblock, Adblock+, Flash Video Downloader, FoxyProxy, Liquid Words, URLFIXer.
