May I suggest https://mojeek.com/ as a privacy respecting alternative that actually has its own web crawlers and indexers.

Obviously floating point is of huge benefit for many audio dsp calculations, from my observations (non-programmer, just long time DAW user, from back in the day when fixed point with relatively low accumulators was often what we had to work with, versus now when 64bit floating point for processing happens more as the rule) - e.g. fixed point equalizers can potentially lead to dc offset in the results. I don’t think peeps would be getting as close to modeling non-linear behavior of analog processors with just fixed point math either.

The Librewolf project is up to date Firefox core with some hardening and the telemetry going back to Mozilla removed - good stuff.
