Silverlight (Netflix) not working after latest Firefox update

After the latest Firefox update (34.0.5), I can't get Silverlight to work on Netflix. I get a black screen with no error codes.

Netflix has a checklist of things to do if you get a black screen (https://help.netflix.com/en/node/95), and I've done all of these things several times -- manually removing Netflix cookies, uninstalling and reinstalling Silverlight (and I used a Fix-It app on the Microsoft website to troubleshoot), disabling ad blockers and virus software, and scanning for malware. I've done all of these things, and nothing has helped. I can play Netflix videos in Chrome, but I think there's no reason why I shouldn't be able to use my preferred browser, especially since I was able to do it without incident up until Wednesday night.

I had two chats with Netflix tech support. Neither were much help, but the second person suggested that I uninstall Firefox entirely and then reinstall. I don't really want to do that. I'm not really that tech-y, and I'm afraid of losing my settings. Honestly, I would cancel Netflix before doing that.

Has anybody else had this problem? Are there any OTHER workarounds or suggestions of what I can try to fix this problem? Also, is it possible to be prompted when there's a new Firefox update.. and not have it automatically updated without my permission? I can't, by any chance, roll back to the version when everything worked fine?

Start with this: https://developer.mozilla.org/en/Bug_writing_guidelines

The main thing is to make the problem very clear to someone who may not be familiar with Netflix. Probably best to file it under Firefox > General, as some of the existing Bug reports I found via that "Netfilx" search are classified. The triage team can re-classify them as they see fit.

And as already posted - https://bugzilla.mozilla.org/enter_bug.cgi - is the place to begin by selecting Firefox.

FIXED! I installed FF 33 and it still didn't work so I let FF look for auto updates and it installed installed FF 35.0 and voila!

Fook, than you for the information ¡. I´ll proceed that way. Regards.

philipp, sorry, I do have flashblock, you're right. I did what you told me to do, and when I restarted, there had been no change. I still get the black screen when I click on any video on Netflix. If this had solved the problem, though, would there be a workaround in flashblock? I mean, would I constantly have to disable the extension to watch videos using Firefox? In flashblock options, there is one that says 'block Silverlight as well,' which I have unchecked. I also have added *.netflix.com to the whitelist in flashblock, but no fiddling with flashblock has helped..

I 'reported an issue with a web site that I use' (here: http://input.mozilla.org/feedback/#sad) earlier today. I don't know.. who looks at that and if that's a useful place to submit problems, and I don't know if those become publicly viewable. I'm not very tech-y either, so I hesitated to file a real bug report. I did just do it now, but I'm not sure how useful the information I provided was. We'll see..

Fook, updating to FF 35 fixed your problem? Argh, mine updated to 35 last night (from 34.0.5 -- I had it on auto-updates, which I've turned off now) and the problem hasn't changed!

fook and tenderprey, I also updated to version 35 and the problem continues. Hopefully, posting this issue at "bugzilla" (wich I already did) would help to solve this problem.

Good to know I'm not the only one having this problem. Let's hope that between our posts, they will start working on solving this problem!

I had the identical Netflix issue on Ff 35.0: black screen with no error codes with Silverlight 5.1.31211.0 enabled (Always Activate).

After disabling FLASHBLOCK 1.5.18, Netflix is fully functional once again.

fins2lr: In my case, there´s an error code (N-8156-6003) that indicates that there´s an issue with the silverlight "plug-in". Also, I do not have the flashblock "add-on" installed. Finally, I ran a test on the silverlight "plug-in" and it worked perfectly (see my comment above). Anyhow, thank you for your advice. Regards.

I am just trying to use the "active view" of hotmail, and it keeps getting stuck. Same black screen everyone else has described. I've tried reinstalling Silverlight, disabling flashblock, nothing seems to work.

What is very different is that I am using a Mac OSX version 10.10.1 . This all started 2 updates ago, I am guessing that would be FireFox V 34.x

I've also repaired permissions, and all maintenance. No changes with respect to the issue.

Regarding this not-so-funny "netflix/silverlight-plug-in/firefox" issue I tend to believe that it´s a firefox issue because it all started with the 34.0.5 firefox version and has continued with the 35/35.0.1 firefox version. For example, I ran a test on the silverlight plug-in and it worked perfectly.

I just tried "safe mode" and found it worked. What other troubleshooting can I do to narrow the problem down closer?

I also tried "safe mode" (that is with add-ons disabled) but didn´t worked. I also ran a "refresh" on firefox 35.0.1 and it didn´t worked either. It´s a nightmare.
