Works on any website. Shows fps, frame time, used memory. Change modes by click
It works, but it is no longer maintained
The script adds to every website a performance counter that can show a frames per second (FPS) value, frame time or used memory.

To use scripts, first you need to install a scripts manager. My advice is Tampermonkey, since I use it too
Tampermonkey installation links for a different browsers, choose yours:
Chrome / Vivaldi Opera / Yandex Browser Firefox Safari Microsoft Edge
Refresh this page and click the green Install button at the top of this page. A new tab belonging to your scripts manager will open. Confirm the script installation
Refresh the page where the script should work
If you are going to use the script frequently, you will definitely be annoyed by it hanging on all websites you use. You can make a list of a websites where the script should work:
// @include *
to // @include https://yoursite.com
. Example: // @include https://reddit.com
