The use of Mozilla Firefox About: commands in the Firefox Quantum browser is very simple. We have mentioned all the Firefox Easter egg features or you can say Firefox about commands in the single page of this article that you can use to perform operations and config tasks. The About commands are URLs that are linked with the internal configuration and functionality pages of the Firefox browser. To see the all About page commands of the Firefox browser you just need to type the about:about command in the URL section and hit enter.
The Firefox About Commands settings page will open with a complete list of available About:commands. It is the same as opening some website links in the address bar of the browser. For example, writing about: config in the Firefox URL bar will show all advanced configuration settings of the browser to tweak it. However, about:config is meant for advanced users, developers, or those following specific instructions. Changing some settings can affect the stability, security, and performance of Firefox.
If you talking about the version of the Firefox browser then we are using Firefox Quantum to perform this article.
However, most of the Mozilla Firefox commands are generally not going to be used by common people but they can prove very useful to you or developers if you want to tweak the functionality of the Firefox browser to make it work according to your requirements or troubleshooting it, in case it shows any glitches.

There is one not listed in about:about –
about:blank
Blanks the page leaving an empty page, can be useful for webpages that are frozen and won’t respond to input and won’t let you leave.
This will continue to be an article with useful information for centuries. Because, sooner or later, Firefox will be forced to return to the path of the extraordinary abandoned “about:config” system. The global popular clamor will demand it… And, by then, in addition to this basic information, you could have completed it with an Instruction Manual that explains in detail what each of the “about:config” options are for.
In this way, you would contribute like no one else until now to the in-depth knowledge of Firefox. And they would do the rest of humanity an immense favor.
