You can't¹. There is a new browser called Orion² currently in private beta that uses the same engine as Safari, which you can use Firefox and Chrome extensions on. It works both on Mac, and surprisingly on iOS. I believe it's the only browser on iOS that allows you to use -some- desktop extensions. I use uBlock Origin with it on iOS and it works good enough.

Use it on desktop myself, big fan of having a vertical tab bar implementation that isn't garish to look at on macOS. And thank god I found Orion, I was using Adguard on desktop and was thinking about enabling their HTTPS filtering behavior but that just seemed like such a bad idea
