How to solve the problem that video content cannot be played on Firefox for Linux
Introduction
I encountered a problem that video content such as Twitter could not be played on Firefox, which is installed by default when installing Ubuntu. Therefore, this time, I will describe the solution to the problem.
environment
OS: Ubuntu 20.04.1 LTS x86_64 DE: GNOME
Conclusion
In conclusion, I could solve it by removing Firefox from the standard and installing it officially.
Method
Step1: FlatPak setup
sudo apt install flatpak
I used flatpak for the first time this time, and it seems that this is a new package format for Linux. Use it to download a new Firefox.
Step2: Download Firefox flatpakref
https://flathub.org/apps/details/org.mozilla.firefox
Go to the URL above and press INSTALL Download the file org.mozilla.firefox.flatpakref.
Step3: Uninstall standard Firefox
sudo apt remove firefox
Step4: Install Firefox using Flatpak
flatpak install ./org.mozilla.firefox.flatpakref
cd /var/lib/flatpak/exports/share/applications

This completes the installation. If firefox is not displayed from the GUI When I logged out and logged in again, the display was confirmed.
