2034066 - [Esr140] [Ubuntu 26] Video fails to play on netflix, error code F7355-1203, and other streaming services

Status: NEW

(Core :: Audio/Video: Playback, defect, P3)

Description

[Ciprian Georgiu, Desktop QA]

Attachment: screenshot with the issue

Found in

• Firefox 140.10.0esr

Affected versions

• 140.10.0esr

Tested platforms

• Affected platforms: Ubuntu 26.04 LTS
• Unaffected platforms: Ubuntu 25.04 LTS

Preconditions

• User is connected to a US VPN
• Firefox ESR is downloaded as tar.xz (not Snap/Flatpak)

Steps to reproduce

1. Launch Firefox and navigate to netflix.com.
2. Play any video.

Expected result

• The video can be played correctly.

Actual result

• Playback fails with an on-screen error message: Error Code F7355-1203.

Regression range

• I will investigate in oder to find a regressan range asap.

Additional notes

• This appears to be specific to Ubuntu 26.04. The issue was not reproducible on Ubuntu 25.04.
• The issue occurs only with the .tar.xz builds. Snap builds on the same OS play video correctly.
• Other streaming services (Amazon Prime, HBO, Hulu) also fail to play video.

While I appreciate the bug analysis in #2038070 for further ideas on where to look, I don't think I got the crippled ffmpeg version installed that does not support the non-free codecs. There's this "WARNING: library configuration mismatch" line, but otherwise, this looks functional to me, including matching version numbers of ffmpeg and the extra codec package.
Also, my FF was installed via a .deb package, not by unzipping a tar.xz.
I also don't have a Netflix account to verify the dysfunctional Netflix video player claimed in this bug.

[Alastor Wu [:alwu]]

Firefox ESR is downloaded as tar.xz (not Snap/Flatpak)

Does this issue also happen on Snap/Flatpak?

This looks like 1893469, could you try this way to update all snaps to see if it helps? Thanks!

Comment 5

[bzzz]

I don't know, I avoid the bloated, sluggish snaps.
But it works with regular non-ESR firefox 1:150.0.2+build2-1xtradeb1.2604.1.deb with minor glitches (cannot search/skip forward on most X videos, but letting them play from the beginning works, pausing and resuming is also possible)

I was not able to repro on snap or flatpak builds.

I cannot also repro anymore with tar.xz builds on Esr 140.11.0 with Ubuntu 26.04.
