I feel like nobody will have to consciously do anything in particular, with the current way how things are going.
- Chromium is the modern IE and developers will primarily be on the hook for supporting it, Firefox support will be an afterthought so some sites will just be broken, moving more users over to Chromium.
- The Firefox marketshare is dwindling, it's likely that the users with proper ad blocking will eventually be a rounding error and therefore quite inconsequential. Especially if there are any more ad-related APIs pushed by Chrome that make users more profitable (e.g. Topics API).
- Even among tech enthusiasts, Mozilla in particular doesn't have very good reputation (e.g. how much they spend on actually improving the browser vs other initiatives) and I don't see the marketshare of Firefox skyrocketing, unless something big happens. New competitors like Ladybird are also niche, though it's a really cool project.
- If Apple ever moves over Safari to Chromium, like Edge did, then that effect will only be amplified.
It's basically non-existing already (less than 4% globally) [1] and with basically zero mobile presence.

I posted this comment some days ago [1]:
To put some numbers on what a 2.54% market share means, Firefox actually tracks this data. See here: https://data.firefox.com/dashboard/user-activity:
> Monthly Active Users (MAU) measures the number of Firefox Desktop clients active in the past 28 days.
> February 10, 2025: 163,203,913 clients
> February 17, 2025: 163,742,671 clients
It's possible some people accept it because they don't know any better, but I have never seen anyone going back once they realize it's possible to get rid of the pollution; I have never heard anyone say "where dit the ads go? I miss them".
So maybe it's just our responsibility as power users to educate our friends more?
This causes the majority of people to only be exposed to Edge/IE or Chrome at work, and use their phones the rest of the time.
