Brand new install of 17.10, love it so far. I especially love the new Firefox browser but I can't seem to get my videos to play on photos.google.com. All I get is a static screen with "This video format is not supported".
I did install Chrome and they do play through that browser, so I know I'm just missing something on my Firefox install. I tested Flash and that seems to work on the Adobe flash test site after I allow it, but I never get a prompt to allow Flash on the Google photos page, I assume they're using something else anyway.
Any ideas?

Finally worked this one out, totally forgot about the unrestricted extras.
After that I restarted Firefox and all was well.
You can check your video codec status at:

After you install the unrestricted extras package the H.264 and MSE & H.264 should be blue with a check.
