Yeah it is great – their sales are pretty good but they kind of hide it but I often pick up a bunch of books from there and then host them on my home server so my family can read the books I bought. Also good to support your local book shop if you can , in my opinion.
I like theming , I am already a Firefox user. I think the sad reality is that for more adoptions , in the order of numbers that chrome puts up , Firefox needs to be a default application ; the common users doesn’t want to customize anything ( my hot take ).
I don’t think it is important that Firefox gets to those numbers as long as they can generate enough revenue to keep going.
