firefox

Issue I recently installed Ubuntu minimal on a new computer, and noticed that sometimes Youtube-videos didn’t work. All “old” videos seemed to work, but newly uploaded videos usually claimed that my browser did not support HTML5. Basically, I could have a video in one tab which did work flawlessly, and a video in another tab which claimed I did not have HTML5 support in my browser. The error message was the something like the following:...

If you are using firefox on linux with a dark theme, unstyled input fields will have black background and white text. Sometimes just white text on white background. According to this bug report it has been this way for the last 17 years. To fix it, pop by about:config and add a new key-value (String): "widget.content.gtk-theme-override": "Adwaita:light". After restarting firefox, things will be as they should be.
