Hulu not loading on Firefox v129 for Windows, fix on the way

If you’re a Hulu fan who loves watching on Firefox, you might’ve hit a bit of a speed bump lately. Users have reported that after updating to the latest Firefox 129.0, Hulu videos are not loading. No matter how much you refresh, clear your cache, or try troubleshooting mode, those episodes just won’t play, instead you’re stuck staring at that frustrating black screen.

The issue seems to be a pesky bug in the latest Firefox 129.0 update, affecting users on Windows 10 and Windows 11 too, as some have pointed out. Strangely, macOS and Ubuntu users can keep binge-watching without a hitch. But for those on Windows, it’s been a Hulu-less zone since the update.

Users have been flocking to forums and social media to share their frustrations, with one saying, “Ads load fine, but the actual content won’t ever start playing.” Others confirmed that this isn’t just a random glitch; it’s a Firefox-specific problem. They even went so far as to test it on Chrome and Edge and found that Hulu worked perfectly there.

But hey, here’s some good news — Mozilla is already aware Hulu is not loading on Firefox. A Bugzilla report has been filed, and it looks like the Firefox team has identified the problem. According to a comment on the bug report, a patch is in the works and will be pushed out to users as soon as possible.

If you can’t wait for the official fix (because, let’s be real, who can?) and are unwilling to try other browsers, there’s a temporary workaround that some users have found helpful. It involves tweaking a setting in Firefox’s advanced configuration menu. Here’s what to do:

1. Type about:config in your Firefox address bar and hit Enter.
2. In the search bar, type media.eme.mfcdm.origin-filter.enabled.
3. Change the value from 1 to 0.

This should fix the Hulu black screen issue on Firefox, at least until the official patch rolls out. But remember, this is a bit of a hack, so proceed with caution.

Interestingly, some users speculated that Hulu might have intentionally blocked Firefox from streaming live TV, possibly due to the ability to fast-forward through ads. However, Hulu support has chimed in, suggesting that the issue is under investigation and not a deliberate block. So, it’s safe to say this is likely just a bug — and not some streaming conspiracy.

Hulu users on Firefox aren’t the only ones having issues. Those on Samsung TVs are also dealing with a ghost update issue, but this has also been acknowledged.
