Recently I’ve been playing some games with my Steam Deck. I was thinking to turn it into more than just a gaming handheld. I want it to replace my iPad, which is just a glorified YouTube and Netflix machine.
So I use the Mozilla Firefox browser to play YouTube and Netflix videos. It works perfectly when on Desktop Mode without any issue.
Then I add Mozilla Firefox to Steam launcher so I can open it when on Gaming mode.
At first I thought it had no issue. The videos play just fine. But when I tried to set the video to full screen, it didn’t work. The size of the video became so weird.
Then I stumbled upon this simple trick to fix it from Reddit. Here’s how to fix it.
- First, let’s enter the
about:configfrom the Firefox address bar. - It’ll show a warning, no need to be scared about it, just click Accept the Risk and Continue.
- Then search for the
full-screen-api.ignore-widgetskey. - The default value is
false. Click theTogglebutton shown in the picture below to set it totrue.
And that’s it. Open the Firefox from Gaming Mode. Play a video on YouTube, Netflix, or Jellyfin. Then set it to full screen. This time it’ll work beautifully!
Final Thoughts
That’s it for today’s post. Hopefully, it’s somewhat useful.
