I am making the first independent browser extension store.

This is a directory not a store.

Thought installations could be done directly on the site

Well then, perhaps you should join https://www.indiehackers.com/group/browser-extension-makers and let them know ;)

I like this idea of curating some of the best extensions listed in the browser stores. Google has not updated their store in years and it is not a great way to find the top extensions. It would be neat to showcase extensions similar to how apple App Store displays their top apps. Keep up the good work Bryan!
