CRX File: What It Is and How to Install Themes and Extensions in Chrome and Edge
If you’ve ever wanted to install a browser theme or extension manually, you’ve probably come across the term CRX file. This is the file format Google Chrome (and other Chromium-based browsers like Microsoft Edge) uses for packaging extensions and themes.
Why bother with CRX files?

You get more control over your browser customization.

Installing a CRX file is usually as simple as dragging it into your browser’s extensions page — though you might need to enable Developer Mode first. The process is quick, and it opens up a world of customization options that the default store doesn’t always offer.
So whether you’re trying to make your browser look amazing or just test a custom tool, knowing how to work with CRX file gives you more flexibility and freedom.
