Title:
TLS problem when using Firefox to open secure YouTube page
Status in firefox package in Ubuntu:
Expired
Bug description:
Hello,
I am using Ubuntu 14.04 with the default Firefox 29.0 browser. This
used to work fine for me in Ubuntu 12.04 but since I upgraded to
Ubuntu 14.04 I am getting this problem that whenever I try to open the
page https://www.youtube.com/ (note that this is https), Firefox
displays some "looking up" or "contacting" message at the bottom of
the screen for an instant and then everything just goes blank. Even
the address bar no longer contains the address which I had entered
(i.e. https://www.youtube.com/).
I then tried installing the Chromium web browser and the behaviour was
identical in Chromium too. I then installed the "links" browser and
tried to open the secure YouTube site in the terminal and "links" was
able to successfully open the site and display the text on the page.
Everything else works fine in Firefox, I am able to open other sites
including secure pages like https://en.wikipedia.org/. It is only
YouTube which is causing this problem.
Update: I have found a workaround for this problem. I compared the
Wireshark log of packets between my Windows and Ubuntu systems and
noticed that the Windows Firefox was using TLS 1.0 and the Ubuntu one
was using TLS 1.2. On Ubuntu, the YouTube server successfully
completed the TLS 1.2 handshake but sent an RST right after the
handshake when my machine tried to send it some "application data". So
I went into Firefox's "about:config" and set
"security.tls.version.max" to 0 (default was 3). This resolved the
problem although I think it's not a proper fix. Either something is
wrong with Ubuntu's TLS 1.2 support or with the YouTube server.
