I have excellent internet connection and is very fast (300 Mbps).

Video playback on firefox (youtube) and mpv is very bad. When I press back button while video is playing, it waits for like 10 seconds and the audio and video become unsyncronized. This problem doesn’t occur with google chrome or with vlc.

Do I need to install some other codecs or libraries?

I installed firefox with dnf and also by downloading binary from Download Mozilla Firefox for Linux — Fast, Private & Free - from Mozilla , both methods didn’t solve the problem

I installed google-chrome

			# Refer: [Installing Chromium or Google Chrome browsers :: Fedora Docs](https://docs.fedoraproject.org/en-US/quick-docs/installing-chromium-or-google-chrome-browsers/)
			sudo dnf install -y fedora-workstation-repositories
			sudo dnf config-manager --set-enabled google-chrome # Enable the Google chrome repository for installing latest versions
			sudo dnf install -y google-chrome-stable

I installed mpv using dnf

Don’t know if you already got your problem fixed, but for what it’s worth,
I’ve been having this same problem in streaming video, and I got it solved installing the non-free ffmpeg package from RPMfusion. Instructions are here, I found them through this forum thread. Good luck!
