Firefox won't play Twitter videos

Posted

Firefox won't play any Twitter videos, either embedded, or directly on twitter.com. Chrome plays the videos fine on this computer.

https://www.youtube.com/html5 shows check marks next to each video format, so I think I'm OK here. When I click on the video, nothing happens, and nothing shows up in the developer console. Turning off security.csp.enable in about:config made no difference. It still fails in Firefox safe mode. No videos work, but here are a couple concrete examples: https://twitter.com/Dodgers/status/1036403166839853056 or https://twitter.com/SkyNews/status/882509461532717056

I'm stumped... where do I go from here? Besides using Chrome, I mean.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

Firefox shows the shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection.

The problem exists in safe mode, so it's not a problem with extensions.

  • click the shield icon for more detail and possibly disable the protection

There is no shield icon present, either before or after trying to click the video.

When I visit the first link and right-click the video, then choose Inspect Element, the Page Inspector highlights this tag in the page:

<video preload="none" playsinline="" style="width: 100%; height: 100%; position: absolute; background-color: black; transform: rotate(0deg) scale(1);" poster="https://pbs.twimg.com/ext_tw_video_thumb/1036403118764777473/pu/img/fnzEHddsQVNJBa8K.jpg" src="blob:https://twitter.com/1957c2d1-2661-4990-9870-2cbd33fe9a47"></video>

Does your Firefox have that tag?

As long as we're in the developer tools panel... you could check for messages in Firefox's Web Console. Click "Console" along the top line next to "Inspector" Or you can open the Web Console using Ctrl+Shift+k).

Then reload the page in the upper part of the tab and watch for error or security messages. (The lines with blue triangles generally are not significant unless you suspect a style rule problem.) Anything that sounds like it could be relevant?

I see that a lot of answers are marked as unhelpful, so there is not much progress so far to troubleshoot this issue.

This is not a normal video as you can see by the code Jscher2000 posted. I had noticed this code as well, but I don't know how blob: data works with videos. I see XHR requests in the Network Monitor to load additional chunks and some requests (application/x-mpegURL) to load stream data.

Interestingly, when I right-click on the the video (on either example page), I get nothing. No pop-up menu, no messages in the developer console. Nothing. It just eats my click. Same for left click.

Well over a minute after clicking the video, the video still-frame changes to "This media could not be played" and these messages finally appear in the developer console:

Hmm, maybe that's related to the delay in loading? Another way to inspect an element is to open the Inspector using Ctrl+Shift+c, which makes "click to select" active.

The Web Console messages suggest that some content is blocked from loading. Is Firefox's Tracking Protection feature kicking in? You would see a "shield" icon next to the padlock at the left end of the address bar in that case. (What happened to Tracking Protection?)
