> When about do you think firefox will no longer build for X?
Firefox? 2025 at the latest. Firefox was the project that deprecated ALSA a few years back. Now that all major distros ship with Wayland as the default, it's time to assume Wayland and not assume X. Eventually X support will become burdensome, and be removed.
You can still build Firefox with Alsa support and probably still will be able to in 2025.
The majority of users are still using x11 which is why for example Firefox just added hardware decoding under X last month. Optimistically for wayland this might change between 2024-26 at which point application developers can stop supporting it at which point people who are so inclined can provide an x11 build of Firefox in 2026-2028 which are liable to work through 2030.
In a less optimal world we are still in step one in 2030.
Anyone who thinks X is going anywhere this decade is dreaming.
