1338784 - Firefox 51.0.1 @ Windows 7 does not work with Vidyo conference system

Status: RESOLVED DUPLICATE of bug 1322167

(Firefox :: Untriaged, defect)

Description

[Alexander]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161208153507

Steps to reproduce:

Upgraded to 51.0.1 . Tried to join a Vidyo room (many times, also different rooms) by pressing a corresponding link on a web page.


Actual results:

The Vidyo session does not start: it hangs infinitely on "transferring data" from the Vidyo server.


Expected results:

I should have entered the Vidyo room (= a video conference).

The problem was cured by downgrading to 50.1.0. 
The following procedure was done twice:
  -- upgrade to 51.0.1 (Vidyo not working)
  -- downgrade to 50.1.0  (Vidyo OK).

Could you provide a public demo of Vidyo or a guest account to test?
It would help to find a possible regression and debug.

Comment 2

The option with a quest login seems possible.
 
I use the vidyo portal http://vidyoportal.cern.ch/ of CERN (http://home.cern/) , and my CERN account to login.

There is a test Vidyo Room called "Vidyo Cafe", with the address
https://vidyoportal.cern.ch/flex.html?roomdirect.html=&key=hsjT7YiPtmp7 , described at the page "Users: Test your setup" http://information-technology.web.cern.ch/services/fe/howto/users-test-your-setup.
The room is supposed to be always on.

One can login to this room as a guest. One finds the procedure on the page "Users: Install the Vidyo Desktop client", http://information-technology.web.cern.ch/services/fe/howto/users-install-vidyo-desktop-client :
"When accessing to a meeting for the first time, you will be asked to install the VidyoDesktop Client. After installation a small Vidyo icon will be available on the system's notification area. In the vidyoportal field one should put https://vidyoportal.cern.ch and fill your CERN account details (username and password). If one doesn't have an account, when invited to a meeting one should enter a random Guest name."

I can not reproduce this issue on my machine:  	Mozilla/5.0 (Windows NT 6.3; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0

Attempted to test on my win 7 Virtual Machine but it is not picking up my camera so I am running into problems there. I can not confirm this on win 7.

I did however have a similar problem last week. After I restarted my computer, things worked fine.

After staying at Firefox  50.1.0 for about two weeks and "enjoying" invitations to update about every 5-10 minutes, I have tried today 51.0.1 again.
The result is the same: Vidyo not working. Neither via my CERN account, nor in the guest mode.
OS reboot did not help either (unless I rebooted to a linux OS where Vidyo started OK with an old FF 45).
Having updated VidyoDesktop from version 3.6.0.027 to the latest one 3.6.9.014 did not change anything.
It is noteworthy that the  latest Chrome 56.0.292487 works fine with Vidyo on my OS (Windows 7 Home Premium).
However, I prefer the Firefox and I am back to 50.1.0 again.

Alexander, as you are able to reproduce the issue on your machine, could you download the tool mozregression to narrow down a regression range in FF51.

See http://mozilla.github.io/mozregression/ for FAQ.

You can try the command-line version (you need to install python 2.7) if you need to create a testing profile with the Vidyo plugin (I don't really know how works this service) to use with mozregression.

Run the command "mozregression --bits=32 --good=50" then copy here the final pushlog from repository mozilla-inbound.

I installed the graphical version mozregression-gui 0.9.6 . I made two bisections for Bits "32" and Build Type "opt" (was "opt" a correct guess?) :
  (a) from version 50 to  2017-02-18 ,
  (b) from 50 to 51 .
In both cases the procedure converged but Vidyo was ALWAYS OK. I guess you do not need any logs under such circumstances.

The continuation was without mozregression.

I tested a new clean firefox profile. Its behaviour w.r.t. the versions 50 / 51 was the same as for my old default profile (Vidyo OK for 50, wrong for 51)..

Then I tested the beta version Firefox 52.0b7 . Vidyo is OK there!
So one can hope the production version 52 will also be fine.  The 53 looks less definite...

It seems to me the same problem is discussed in the
 "Bug 1322167 - Vidyo guest links unable to connect to Vidyo desktop client "
 https://bugzilla.mozilla.org/show_bug.cgi?id=1322167

Let's dupe it.

Comment 9

[Loic]

I think I know why it doesn't work in your current profile.

Type about:config and report the value of the string security.mixed_content.send_hsts_priming.
I guess Vidyo is broken when it's true.
