Why firefox 33 do not open any films (FLV or WMV)
Not one link to a film with the extension FLV or WMV works I cleaned my cache I reinstalled VLC but the older versions firefox 2.1.3 keeps coming up. I installed again windows movie plug in what not is showing up in the list. I reinstalled firefox and still no movies only a big list of characters on my screen. It looks like firefox don't like movies :-)

Firefox shows the file content in a tab instead of playing the file if the server is sending the file as text/html or text/plain. You can verify that in "Tools > Page Info > General" with such a file in a tab.
You can't play (open) such a file link directly in a tab in such a case. You would have to use other ways to force Firefox to use a plugin in such a case like using a keyword bookmarklet that specifies a content type that the plugin supports.

Sir
I'am a simple user and see that Chrome, comodo dragon en IE support these files and show me the films. So because I'm not a programmer I can't do anything with this information. Please let me know in understanding language what I have to do.
What means keyword bookmarklet? What means specifies a content type that the plugin supports? VLC and windows players are installed What I have to do with this? data:text/html,<object type="application/x-mplayer2" data="%s" width="100%" height="100%"></object>
This is not a answer sir for normal users.

MozillaZine's Testing plugins article links to some media test pages.
Does this FLV file (linked from this test page) work for you?
What about this WMV file (lined from this page)?
If the files linked from the above pages work but others don't, the problem might be a misconfigured server for the files that don't open properly. Could you post some links?
Alice Thank you for your test links Your test links working but what is the problem?

The problem is that your web server is using "text/plain" instead of the correct MIME type (content-type), which would be video/x-flv for .flv files and video/x-ms-wmv for .wmv files.
Contact the service provider or webmaster for your website and refer them to this thread or to https://developer.mozilla.org/en-US/docs/Web/Security/Securing_your_site/Configuring_server_MIME_types
I'll mark the answer by cor-el as solving this question, since he figured that the server is sending the file as text/html or text/plain.
Thanks Alice I will make a ticket to Lunar pages and send them your message
Thanks for the good support
