¡Hola!

Given now you can Watch DRM content on Firefox, you might want to give it a try with Silverlight uninstalled.

I myself had trouble with Netflix today. What fixed the issue for me was deleting all Netflix cookies, see https://support.mozilla.org/en-US/kb/delete-cookies-remove-info-websites-stored#w_delete-cookies-for-a-single-site and then forcing a refresh of Netflix a couple times <Ctrl>+<F5>.

Let us know if this solves the problem.

¡Gracias!

I removed all the netflix cookies and also silverlight. I am sorry to say it did not work. Thank you so very much for your help.

¡Hola Paul!

What's the error message Netflix shows?

Have you tried to contact Netflix support yet?

¡Gracias! Alex

Hi Alex, There are no error messages, just the black screen. Contacted Netflix yesterday. 2 techs worked on it but couldn't figure it out. They recommended I goto the forum and hope for help. You are the only one who has tried and I wish I could tell you the problem was solved. Have even tried to load an earlier Firefox, but it always ends up being #42, Maybe I'll try again withou the internet on.

Thank you for being there. Paul

¡Hola Paul!

Could you please give it a try with https://nightly.mozilla.org/ ?

Netflix works for me there sans' Silverlight.

¡Gracias!

worked right away. thank you SO VERY much Paul

¡Hola Paul!

Glad to hear it worked.

If you do not want to stay on the bleeding edge of Firefox that is Nightly, you might want to check if the issue is resolved on https://www.mozilla.org/en-US/firefox/developer/ or https://www.mozilla.org/en-US/firefox/channel/

If you stick with Nightly, it will update daily and things might break occasionally.

I've personally been using Nightly as my daily browser since 2008 with no major issues but this is not for everyone.

¡Gracias!

Nightly used to work; then it was upgraded on 11/28 and hasn't worked since. Now it tells me it is updaying video and sound and to try again later. Later never happens. Same thing as on Firefox. I hate to change to Edge, but it works and I haven't found a way to tell Mozilla of this problem. Thanks again Alex

¡Hola Paul!

Sorry to hear it broke.

Does Netflix give you an error code?

¡Gracias!

Finally I reset win10. Lost all my stuff and am reinstalling. Now everything works fine. Somehow I must have done something to Win10. So glad that is all over. Thank you so very much for bearing with me all these weeks. ] Gracias! Sorry about the leading exclamation mark.

Paul
