Enable flash player in Konqueror
From Manjaro Linux
Konqueror is KDE's file manager and web browser. Unfortunately flash player doesn't work out-of-the-box in Konqueror, you must enable it in settings.
- Open konqueror and go to Settings>Configure Konqueror.
- Go to "plugins" and click "scan" button and then "ok". Close settings window.
- Done! Now all should work, and you can finally watch video from YouTube.
