I have experienced this bug myself when testing the most recent beta on Mac 10.8 but there are also reports in input.mozilla.com that indicate it has been happening to others starting with FF 13:

I get error N8008 from Netflix telling me I am viewing Netflix from more than one tab when I am not. I have to restart Firefox to fix this. It only started happening after Firefox upgraded to 13.0.

There seems to be some run-on after closing a browser/returning to browse movie lists when using Netflix. Netflix informs me that I have multiple browsers open to their site when I try to view a new movie. [back to browsing] - select movie - error.

I have sent an email to my contact at Netflix advising them of the issue so we will wait to hear back.
I believe when it happened to me on 10.8 I was doing the following:

1. Logged into netflix.com account.
2. Start streaming a movie.
3. Move into full screen mode.
4. Use the arrow in the upper left hand corner of the UI to go "Back to Browsing"
5. Choose another movie to play
6. Received the attached error.
I was able to reproduce the STR in Comment 1 on a Windows 7 machine so I have now seen it two machines. Next step is to see what happens using FF 12.
I spent some time on Mac trying to reproduce this using Firefox 12. I was able to reproduce this using Firefox 12 (the error is different, but seems to be the same issue). So the issue does not seem to be isolated to FF 13 as one comment indicated.

The STR are the same as in Comment 1 except I did watch the movie in HD mode. Silverlight version running this machine is Version: 5.0.61118.0.
Summary: Firefox 13 beta: Netflix video errors "you are viewing from more than one tab" → Firefox: Netflix video errors "you are viewing from more than one tab"
Starting this off in Core/Plug-ins - hopefully we can get somebody to look at this in a debugger to figure out if it's a site/plugin/browser issue.

Is this mac-only or does it happen on all platforms? Is it much more common in Firefox 13? Bug 90268 was intended to change plugin instance lifetime, so if you're looking for regression ranges I'd start there.
I have been able to reproduce this on Windows 7 (see Comment 2). I tried again today and it was able to do so using a Win 7 lab machine running the latest Firefox beta with Silverlight Version: 5.1.10411.0 (the latest). On Mac I have been able to reproduce with earlier versions of Silverlight.

As far as whether it is more common in FF 12 versus FF 13 I will have to do some further testing to answer that question.

Netflix also made some changes to their player recently - see http://blog.netflix.com/2012/05/updated-web-video-player.html.

If Bug 90268#c274 didn't isn't yet in FF 13, does this mean the issue is likely site or Silverlight-related?
It isn't in Firefox *12*. As far as I know it is in Firefox 13. But given the details we have so far, this seems likely to be site-related.
I have encountered this bug for more than a week at least in Fx14 (win7-64) as well.Seems to have disappeared though.

Can you check to see if you can reproduce this in Firefox 13.0b5?

I was able to reproduce the issue using the latest beta on Mac OS X 10.8, so I think the issue is still hanging around and seems likely to be site related.
Would it be possible to do some outreach to confirm?

Marcia let me know she's able to reproduce intermittently - what info can we get from her when the error occurs to help with debugging?
Well I couldn't do it on Fx13b5 with the steps listed in post 2, and it has also disappeared in Fx14.
Marcia, is there any extra information you can provide to help in the debugging process?
I haven't been able to reproduce consistently - actually only reproduced this once. I will try again today on the 10.7.4 lab machine where I was able to reproduce it once.
I believe Juan contacted Netflix customer service yesterday since he was hitting this error and he was told it was some sort of cookies issue.
I haven't been able to reproduce this problem, but I contacted Netflix about a different issue which I was experiencing in one machine all the time. Their support person asked me to go to: www.netflix.com/clearcookies which upon loading redirected me to a sign-in page. And after login in and trying to play a video, things worked again.
Awesome, we'll document this on our end.  Thanks.
