How To: Install a Developer Browser Extension
Download and uncompress the file
Download the zip file for the extension and double click to unzip.
Install the Extension
In your Chromium browser (Chrome, Brave, Arc, etc.), open the Extensions page and find and enable the toggle for “Developer Mode.” Once that’s enabled, locate a button titled “Load Unpacked” and point it to the folder created when you uncompressed the file.
Done!
That’s all there is to it.
