Of course! I don’t use extensions, but I’m sure most of the big players you’d expect from chrome have a Firefox version as well. Here is uBlock Origin https://addons.mozilla.org/en-US/firefox/addon/ublock-origin...

Apparently Mozilla vets add-ons with their ‘Recommended Extensions program’, not sure how you get an extension into that program though.

Here is Pushbullet for Firefox! https://addons.mozilla.org/en-US/firefox/addon/pushbullet/

chrome purposefully breaks some privacy oriented extensions.
