Only popular religions ;)

I agree. I pointed out that your statement "You can only install extensions from their store" is incorrect for Chrome. Thank you for adding information about Edge.

Ah, haha, yeah, that's fair. I usually disregard things that are "heavily discouraged" behind developer modes and checkboxes buried deep in menus.

Enabling local extension install in Chrome is a single checkbox at the top of chrome://extensions -- the same place where you manage the rest of your extensions. But point taken.
