earlier, we could use extensions(except for 7-8 highly poplar ones) with an account containing add-ons collection(in nightly versions). But now it's coming to beta and stable as well.

collage of Mr bean waiting in the field with the text "Me waiting for more extensions in Firefox for Android."
below is another Mr bean image, this time excited, sitting in a plane with the text that reads "they are arriving in version 120."

I hope we'll get to use LibRedirect, it does exactly that, but for a dozen or so services
