Firefox's about:config preferences and understanding them better.
I'm interested in learning more about Firefox's about:config configuration settings. I'm especially interested in why the developers have added the ability to create your own preferences for Firefox. It seems to be kind of similar to the Microsoft Windows registry, like how you can add your own custom values and suddenly windows behaves differently. But whenever I have configured the registry in windows, I have always had to follow tutorials, and I have always wondered how people were able to discover those registry settings. Did they have to have knowledge of the internals of the windows operating source code? Did they hack windows and discover that altering a certain registry setting, or adding a certain registry value, would cause the behavior to change? How did they come to understand such things? I recently edited the registry to change the right click menu in windows 11 back to the old windows 10 right click menu. I had to add a really long value into the registry, and it fixed it just like what I was used to in windows 10. But I have no idea how the person that wrote the tutorial knew to add that exact value.

At one time about:config was regarded as one of Firefox's virtues. You can search any preference on the following site (remove the blank space in the link). https://searchfox. org/ AFAIK, you cannot create any preference of your choice, it has to one recognised by the software. You don't need to study the source code.
