For what it's worth, Pale Moon can still be built for 32-bit Linux ( fish through contributed builds, or build your own). Sufficient for many, many sites, although a few will break or require workarounds.

Yup, i personally own various 32 bit machines that are completely usable in daily driving but the steady decline of supported programs to run on them is forcing them into more "retro computing" roles. Honestly, its a shame...
