I tried the link you posted and had no problem. Normally when you right-click on the player, it identifies itself. But this player did not.

Make sure you are not blocking content

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

No luck but thanks for trying. I can go through the link you posted again to make certain I didn't overlook anything. That website CBC gave me this info, not sure if this will mean anything to you but this is what they said. "For video we use segmented MP4s delivered using HLS.

For support you therefore need a Browser / OS that supports the HLS or the Media Source Extensions (MSE) Standard."

Firefox relies on built-in OS support to play media files via the HTML5 media player. On the Windows XP platform you do not have native support for playing MP4 files with the HTML5 media player.

You can try if the solution posted here to add support for playing MP4 files works for you.

'What I don't understand if I don't have the support to play those MP4 files with the HTML5 player why is it on that CBC.ca website do the videos work if I switch to the old Google Chrome 49 browser with no problem? It makes no sense to me. Those directions on that website on how to do this are a bit tricky meaning for someone who doesn't know a great deal about computers like me have a little trouble with. I will try to study it better again. If I can't figure out then I guess I'm stuck with having to use the Google Chrome until I can try and save up some money for a new computer for some time in 2018. I can see that I have a lot to learn when it comes to computers, I thank everyone who has been trying to help me, I'm sorry if I bothered anyone, again, I wasn't trying to be a pest to anyone.

Here is my understanding: anyone distributing a decoder for H.264 video needs to pay royalties to the owner of the patent on that codec. Mozilla believes that is inconsistent with an open web and refuses to enter into such a license. Therefore decoding in (open source) Firefox needs to be done through external components that are properly licensed. Google pays for a license, and therefore it gets to include the decoder directly in (not open source) Chrome.

Getting the FF profile is no problem, following the rest of these directions and it's either not working or I'm not 100% doing something right. Open your FF profile folder. An easy way to navigate to it is by opening about:support in FF and clicking the Open Folder button next to Profile Folder.

   Inside the profile folder, create subfolder gmp-eme-adobe and open it.
   Inside gmp-eme-adobe, create subfolder 17 and open it.
   Unpack the Primetime ZIP archive into folder 17.
   Folder [your FF profile path]\gmp-eme-adobe\17 should now contain three files: eme-adobe.dll, eme-adobe.info, eme-adobe.voucher.

Here's a little more on those steps:

(1) Inside the profile folder, create subfolder gmp-eme-adobe and open it.

First, select and copy (Ctrl+c) the following new folder name:

gmp-eme-adobe

Right-click a blank area of the folder, choose New, then Folder. Windows should select the name. Use Paste (Ctrl+v) to change it to gmp-eme-adobe and click away to complete the edit.

(2) Inside gmp-eme-adobe, create subfolder 17 and open it.

Double-click the new gmp-eme-adobe folder to open it. Then create a new folder here named 17 (literally, the number 17) using the same method: right-click a blank area of the folder, choose New, then Folder. Windows should select the name, type 17 and click away to complete the edit.

(3) Unpack the Primetime ZIP archive into folder 17.

If you have an archiving program like WinZip, 7zip, WinRAR, etc., you can copy the .zip file you downloaded into the 17 folder, then "extract" all of its contents into the folder. Often this will be a choice if you right-click the .zip file, for example "Extract Here". Alternately, you can open the .zip file in your archiving program and use the extract feature to put the files into the 17 folder.

(4) Folder [your FF profile path]\gmp-eme-adobe\17 should now contain three files: eme-adobe.dll, eme-adobe.info, eme-adobe.voucher.

After extracting, those three files should be found in the folder.

If you copied the .zip file here, you won't need it any more. Perhaps put it in your Downloads folder or somewhere else for safekeeping.

I thank you very much for trying to help me. Yes, I did all of this, the folders are all there just as you say but it did nothing for the videos in this link: http://www.cbc.ca/news/canada/newfoundland-labrador/programs/hereandnow I still get a black screen and it says the selected item is not currently available, so I tried to disable Flash Player to see if that would help, it didn't so I turned it back on. I refreshed the website, still won't work, the videos on that website still won't work, the only time it will ever work is when there's a Live Stream but the only reason why is because when it goes on Live Stream CBC seems to be using a different media player/format. Now when I go on to Google Chrome 49 to that link that I mentioned above the videos play fine without me having to do anything but you explained that to me the difference between Fire Fox and Chrome so I now get that. I know there's nothing wrong with those files I added to that new folder/17 as you instructed because my Norton/Symantec would've told me. I don't see how I could've messed this one up, you made the directions simple/easy to understand. Again, I'm on Windows XP 32bit Firefox 52.4.0 ESR I do thank you for all of your efforts, it was very kind of you to try again. What's strange is that I don't see this program in the adds on. I went to tools, add ons. Something is telling me I might have goofed but I don't see how, I can see the files when I go to the Fire Fox profile folder. Why could I have possibly done wrong this time?

Could you try something simpler first... could you scroll down this page and try the H.264/MP4 test video:

I just came back from rebooting the computer but no luck. I just clicked on this link to test video you posted and it says no video with supported format and MIME found. I don't understand how I could've messed up, you made the directions quite clear. Do you think I did something wrong again?

I just checked my add ons and I don't see the Primetime Content Decryption Module plugin by Adobe. Perhaps there are more steps I need to do in addition to the directions already given? I really thank you for going the extra mile trying to help me. Well, at least I got the part to where those files are in my Fire Fox profile so that's some progress anyway. I'll wait for any possible further instructions. Thank you so very much again for being so kind and patient with me.

This is very strange, now this video link doesn't work at all on both Fire Fox and Google Chrome49 http://www.cbc.ca/player/play/2641927757 Yet all the videos in the link below do Not work at on Fire Fox but still work just fine on Google Chrome 49. It seems like CBC is messing around with websites. Maybe different formats. http://www.cbc.ca/player/news/Canada/North

Anyway, I'll check back again and wait to see if there are any possible further instructions, thanks again, at least those files are in the Fire Fox profile.

Did you modify all the prefs as described in the link of that website?

I followed the directions that were posted to me. That website isn't 100% clear, it has lines crossed off some things, therefore it's not 100% clear on how to modify all the prefs. The folders however are there, I checked the Fire Fox profile so I know at least that part is right.

These prefs look like the most important:

• media.gmp-eme-adobe.enabled (boolean, true)
• media.gmp-eme-adobe.forceSupported (boolean, true; FF 49.0+)
• media.gmp-eme-adobe.visible (boolean, true; FF 49.0+)
• media.gmp-eme-adobe.version (string, 17; required for manual install now that automatic install is no longer an option)
• media.gmp.decoder.enabled (boolean, true)
• media.eme.enabled (boolean, true; defaults to false if you downloaded a DRM-free version of FF; thanks @heinoganda for pointing this out)

Can you post the path to the "17" folder and possibly provide a screenshot to confirm that the files are in the correct location?

How do I go about trying to do this? It says root directory and local directory under about profile. Remember, I'm not a computer wiz, my knowledge here is limited. The folders were created in the exact place where jscher2000 told me to do it as this person has been very kind trying to break things down to make it simple for me. I'm not sure how to take a screenshot but one thing I do know for sure when I click on the profile folder on Fire Fox those folders that he told me to put are there, I just checked it again now.

It is probably OK, but a screenshot of this folder in Windows File Explorer for confirmation never hurts. Proper Troubleshooting includes verifying that everything is correct (files and prefs in this case).

Those are two completely separate things, actually. Preferences are settings inside of Firefox.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste gmp and pause while the list is filtered -- any preferences starting with media.gmp should appear.

(3) If a preference is missing, then you need to create it. That is why the information in parentheses is there. For example:

• media.gmp-eme-adobe.enabled (boolean, true)

To create that preference:

(A) Select and copy the preference name

media.gmp-eme-adobe.enabled

(B) In a blank area of the about:config screen, right-click and choose new, then the "type" listed in parentheses, which is Boolean

(C) Firefox will display a little form to paste in the preference name, then click OK

(D) Firefox will display a form for the preference type, so for Boolean, you can choose between true and false (in this case, you want true) then click OK.

Then repeat with any other missing preferences:

• media.gmp-eme-adobe.forceSupported (boolean, true)
• media.gmp-eme-adobe.visible (boolean, true)
• media.gmp-eme-adobe.version (string, 17)
• media.gmp.decoder.enabled (boolean, true)

(5) In the search box above the list, type or paste eme. and pause while the list is filtered

(6) If needed, change the value of the following preference to true, or create it:

• media.eme.enabled (boolean, true)

Someday you will be teaching this to other people. Or someday XP will cease to exist and we can all stop talking about it.
