Well, Chrome does have extensions, including Nos2x and Alby, but it's only available on desktop. The android version doesn't have it. And Kiwi was the only mobile browser that offered chrome extensions, but the devs stopped maintaining it last March or April and FFbrowser has it marked EOL and isn't offering it for download anymore. Discussions on their github repo also indicate that it's a dead project. So now there are no chrome/chromium browsers that support extensions. Cromite is considering adding that support, but there's no ETA on when that will be done.
