Just tested in an up-to-date 18.04 virtual machine, and I can play the sample videos on gaia.com's home page.

Also, please run the following command in a terminal to attach additional information to the bug report: apport-collect 1834375 Thanks! ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834375 Title: Gaia.com videos unsupported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1834375/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
