Hi, I don't know what silverlight is. I just updated my firefox and now netflix won't play...

J~
I have been able to reproduce this issue so far on only one 10.6 machine in the QA lab. It does not reproduce on my 10.6 laptop with the same Silverlight version/9.0.1. Machine specs on the machine where it reproduces:

I have an intel core i3....Silverlight 5.0
One tester reports:

The plugin container process is returning an error to the system console, only when it fails:
"unknown error code: invalid display"
Marcia, Naoki:

Could one of you try to find a regression range in mozilla-central nightlies?

And perhaps also a "degression" range, if the problem no longer exists with current trunk code?

Note that Silverlight pays attention to the user agent string, and (because of this) has in the past misidentified mozilla-central nightlies as not being Firefox.  So you should set your user-agent string to that of a Firefox release for at least some of your tests on mozilla-central nightlies (and perhaps also other kinds of nightlies).

More in my next comment about how to set the user-agent string.
Here's how to make any version of Firefox (including mozilla-central
nightlies) use FF 9.0.1's user-agent string:

1) Run FF 9.0.1 and visit http://browserspy.dk/browser.php and copy
   the "navigator.userAgent" string (up to but not including the final
   '.' character).

   On OS X 10.6.8 this is:

   Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:9.0.1) Gecko/20100101 Firefox/9.0.1

2) Quit FF 9.0.1 and run the version of Firefox you wish to test with.

3) Enter "about:config" in the location bar and click the "I'll be
   careful" button.

4) Right-click (or ctrl-click) on the settings panel and choose New :
   String.

5) Enter "general.useragent.override" as the "preference name".

6) Enter the string you copied in step 1 as the "string value".

7) You need to restart Firefox to make this change take effect.
Here's FF 9.0.1's user-agent string over again, hopefully this time without a line break in it:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:9.0.1) Gecko/20100101 Firefox/9.0.1

Seems like it would be a lot easier just to use User Agent Switcher addon : https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher/ and change the user-agent string that way.  Would that be ok, Steven?

Sure.  Any way that works to set the user-agent string is just fine.

But however we do it, it's really important to test nightlies with a release user-agent string.  It may turn out that this bug *isn't* fixed in current code.

It's really important to test this way with both nightlies and
"pre-releases" (e.g. alphas and betas).
And in the Mac Console App I get this error, not sure if it is useful.

Now back to our regularly scheduled regression hunting.
From what I can see, Netflix works in the current trunk nightly when I change the UA to 9.0.1. It also works without changing it as well.

That's good news.  I hope you tested on a machine where you're able to
reproduce the problem with "genuine" FF 9.0.1.
Yes, testing on the same 10.6 machine where I was able to reproduce on the real mcoy:  Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:9.0.1) Gecko/20100101 Firefox/9.0.1.

Changing Firefox 9.0.1's user agent to match Safari 5.0.5 [ Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_8; de-at) AppleWebKit/533.21.1 (KHTML, like Gecko) Version/5.0.5 Safari/533.21.1 ] based on info from : http://www.useragentstring.com/pages/Safari/ allows the video to play ( I had to log out of netflix first )  In fact, using the string that you provided worked as well.  

What did not work was the default User Agent.  Could it be that there was some kind of control character introduced inside the User Agent that is installed with 9.0?
Please ignore the part about the control character.  It appears that something was cached.  

The safari user agent does work with 9.0.1.

Comment 29

I had the latest silverlight (5.0.61118.0) installed on a 2008 MBP with OS 10.6.8 and Firefox 9.0.1. Netflix would not play (just got a black screen). I quit Firefox and and restarted it in 32-bit mode. Then Netflix videos played just fine.
Marcia and Naoki, were you testing in 64-bit mode?  Does FF 9.0.1 also
work for you in 32-bit mode on machines where it doesn't work in
64-bit mode?  (Here I'm talking about tests with the default
user-agent string.)

As I understand it, Silverlight uses the Cocoa event model when it
thinks it's running in Firefox, but otherwise uses the Carbon event
model.	I suspect Silverlight uses the Carbon event model in FF 9.0.1
when you make FF 9.0.1 use the Safari user-agent string.  So it seems
this bug only happens when Silverlight uses the Cocoa event model.

So the puzzle is why Silverlight works in current trunk code with the
FF 9.0.1 user-agent string, when presumably it's using the Cocoa event
model.  It's very important to find out when this change happened
(i.e. to find the "degression" range) -- even more important than
finding the regression range.  (Though of course it'd be nice to have
both.)  Remember that when finding the degression and regression
ranges, you'll need to test with FF 9.0.1's user-agent string.
And needless to say, all tests should be done with the current version of Silverlight (5.0.61118.0).
Yes, I was testing in 64-bit mode. I will do some tests today in 32.

At Cheng's suggestion I tested Firefox 8.0.1, 10b3, 11, and 12 in 64bit mode and with the default UA and they could all play netflix movies with silverlight (5.0.61118.0). I also tried all of them with the 9.0.1 UA and again they could all play netflix movies.

Comment 34

I just went back and tested Firefox 8.0.1, 10b3, 11, and 12 in 32bit mode with both the default UA and the 9.0.1 UA and they were all able to play netflix movies.

So far the only combination that I've been able to reproduce the problem with is 9.0.1 in 64bit mode.

Yes, I was using 64 bit mode.  on 10.7, it stated that I had to use Silverlight in 32 bit mode and worked.  on 10.6, it didn't state that at all.

For the record, all the tests I did were on a late 2008 MBP (first unibody model) running Mac OS 10.6.8
Testing with the lab machine where I was able to reproduce the issue, Firefox 9.0.1 plays video fine in 32 mode but not in 64-bit mode. Testing with Version: 5.0.61118.0.

I also tested with Firefox 9 and I see different behavior in Firefox 9 versus 9.0.1 relating to Netflix. Loading Netflix in 9.0 I do not see a black screen, but I at least see the Netflix player. This is in 64-bit. Attaching a screenshot shortly.

It'd be worth doing some tests with the FF 9 user-agent string (as opposed to the FF 9.0.1 user-agent string).

I just tested 9 on my machine and didn't see this. I got the same results as 9.0.1 - works in 32-bit mode, black screen in 64-bit mode.
I've written a debugging patch, and have been playing around with Silverlight examples at http://www.silverlight.net/showcase.  Testing on OS X 10.6.8 in 64-bit mode, it tells me that, in current trunk code, the current version of Silverlight always uses the Cocoa event model (and the CoreGraphics drawing model), regardless of what user-agent string you use.

I'll apply my debugging patch to FF 9.0.1 and 9.0 code, and see what results I get.
I've also confirmed that Silverlight 5.0.61118.0 doesn't turn on plugin caching.  So, as far as browser code is concerned, there isn't any difference for Silverlight between FF 9.0 and FF 9.0.1.
(Following up comment #30)

Turns out this is wrong for both Silverlight 5.0.6118.0 and
Silverlight 4.0.6831.0 (which I	believe to be the last v4 version, and
was released late last year).  I found this out by testing with my
debugging patch in current trunk code, FF 9.0.1 code and FF 9.0 code.

In 64-bit mode, Silverlight (v5 or v4) always uses the Cocoa event
model with all three of these builds.

Interestingly though, in 32-bit mode Silverlight always uses the
Carbon event model.  (Actually it doesn't request any event model,
which means that we default to using the Carbon event model in 32-bit
mode.)  This makes sense, because (as I didn't remember earlier) the
Carbon event model is incompatible with our implementation of IPC, so
(Silverlight being 32-bit only on the Mac) the Carbon event model
won't work in 64-bit mode.

So it looks like what I said about the user-agent string was a red
herring.  Silverlight may still attention to it, but not in the way it
used to.
I wonder if Silverlight settings/preferences could make a difference
here -- particularly settings inherited from earlier versions of
Silverlight.

Silverlight preferences live in
~/Library/Preferences/com.microsoft.silverlight.plist.	And
Silverlight stores other information in	~/Library/Application
Support/Microsoft/Silverlight/.

Whoever can reproduce this bug, please try again after having renamed
this file and directory.
(Following up comment #43)

Another interesting thing I discovered (that I forgot to mention above):

In 32-bit mode Silverlight turns on plugin caching.  It doesn't do this in 64-bit mode.
Renaming both of those directories did not make a difference in my case. Testing on one of the same 10.6 lab machines where I was able to reproduce the issue.

I can't do much further investigation, since I can't reproduce this bug -- my Netflix account doesn't support streaming.
Summary: [Mac] Netflix not playing videos using 9.0.1 with some hardware → [Mac] Netflix not playing videos with some hardware
Version: 9 Branch → Trunk
OK, I now have access to a Netflix account that supports streaming.
But I still can't reproduce this bug.

I tested on OS X 10.6.8 with FF 10.0 and today's mozilla-central
nightly, in 64-bit mode (the default).  I logged on to Netflix and
then clicked on one of the movies displayed -- which caused it to
start streaming.  All my tests started in non-fullscreen mode.  But
switching to and from Silverlight's fullscreen mode seemed to make no
difference.  I never saw any problems.

The 6-months-old MacBook Pro I tested with has two different kinds of
video hardware.  From the System Profiler:

AMD Radeon HD 6750M
Intel HD Graphics 3000 (built-in)

I used the gfxCardStatus app (http://codykrieger.com/gfxCardStatus) to
force Firefox to use one or the other of these graphics "cards".  It
made no difference -- I didn't see any problems with either graphics
"card".

My Silverlight version is 5.0.61118.0 (which I believe is current).

Try using Fx 9.0.1. I was only able to reproduce this issue with 9.0.1.
I can't reproduce using FF 9.0.1, either.

So Verdi, are you telling us you can no longer reproduce this bug in FF 10.0?

I did a bunch of testing a couple of weeks ago - comment #33 comment #34 and comment #36 and I was only able to reproduce this with 9.0.1 running on Mac OS 10.6.8 on a late 2008 unibody 15" MBP.

I haven't tested this again since then. I can try it with Fx 10 later this evening.

I just tested again: 2008 unibody MBP running 10.6.8. I tried Netflix streaming using 9.0.1 64-bit mode - black screen. Download update to 10.0 and restarted. Netflix streaming worked as expected. 

One other note: The graphics settings under Energy Saver are set to "Higher Performace" so I guess that means the computer is using the NVIDIA GeForce 9600M GT instead of the NVIDIA GeForce 9400M

Thanks for the info.  On the strength of this and what you said in
comment #34, I'm marking this bug WORKSFORME. 	

But we still don't know whether (or how) the Silverlight plugin still
attempts to sniff which browser it's running in, and if so how it
behaves differently if it thinks it's running in Firefox.  So there's
a chance (hopefully only a small chance) that this bug will show up
again in FF 11.

Not necessarily.  The only way to be sure which	graphics hardware
Firefox is using is with the gfxCardStatus app mentioned in comment
#53.  And even that app sometimes doesn't work properly unless you set
it to load on startup (the default) and reboot your computer.

Please use it to test FF with both kinds of graphics hardware.	If you
find that you can still reproduce this bug with one of them, in FF
10.0, please reopen this bug.

Sorry - what you did was comment on an issue (but report) that was resolved about 3 years ago. The support folks use a different website (https://support.mozilla.org). You can also access it from Firefox by going to the help menu and choosing Firefox Help.

This is a direct link to the place to ask a question about Desktop Firefox - https://support.mozilla.org/questions/new/desktop
