In Google Chrome, Where is about.config (firefox) settings?

Firefox has advanced settings that can be accessed by typing about:config into the address bar. It has all of the experimental hidden features.
If you try to access the same in Chrome then you will end up with the following message: "The webpage at chrome://config/ might be temporarily down or it may have moved permanently to a new web address." This is because Chrome lacks hidden and dedicated configuration features at about:config

So, I'm going to show you how to get to those advanced hidden features settings in Chrome.

You can access the Google Chrome Settings page by clicking on the three dots in the upper right corner and then selecting Settings. This setting will provide you with limited features such as Autofill, Security and Privacy, Appearance, Search engine, Default Browser settings, and On startup.

Reminder: If you're uncertain about the changes you're making to the settings, it's advisable to refrain from making any adjustments. If you're unsure about your actions, consider creating a backup of your Chrome settings as a precaution.

If you want more advanced hidden experimental features with more options, then follow the steps below:

1 Open Chrome browser and type about:flags or chrome://flags in Chrome’s address bar and press Enter

This will take you to Chrome's advanced configuration or Experiments page. You have two tabs: one that says Available and one that says Not Available. We can only make changes to the features listed under the Available tab. You have the option to enable or disable experimental browser features.
