One of the main arguments brought forth for the switching to the WebExtensions system for browser extensions was that it made cross-browser extensions easier. Firefox users may now reap the benefits of this promise, as Mozilla has implemented functionality in the browser to import extensions from other browsers.

The feature, which is in testing at the moment, can be enabled by all users of the latest stable version of Firefox.

The feature is limited at the time to Google Chrome and select extensions. Even though Firefox and Chrome extensions use the same framework, WebExtensions, they are not compatible immediately. Firefox users who attempt to install extensions from Chrome’s Web Store may notice that this is not working.

    The extensions are JavaScript - you can check the code yourself.

        Eh? Firefox supports Manifest V3 as well. I don’t find anything naive about it. Firefox supporting Chrome extensions can only help Firefox.

            Nope, what benefits Firefox is when something is working on Firefox.

            As an example, I use Revolut and most importantly the one-time virtual cards by Revolut. They have a nice Chrome addon that lets you fill the card details. Otherwise I have to get my phone, open the app, authorize with PIN, check the card details, authorize with PIN again, rewrite the card details and check that I didn’t make a mistake. If the Chrome addon worked in Firefox, it would make my life significantly easier. Sure, the ideal scenario is Revolut supporting Firefox themselves but for whatever reasons they don’t want to.
