General discussion • Re: RPi 4 improving performance and battery runtime?

As mentioned, Raspberry Pi OS, desktop, 64-bit.

As mentioned, use case is browsing sites like these forums, Reddit, news, etc.

I noticed Firefox says it is 32-bit, is that a performance issue?

Where are you seeing this? I've just launched Firefox on RPiOS 64-bit and about page says "Firefox Browser (aarch64)".
So that is a 64-bit build.

I've figured this out at least.

On my old microSD card (Samsung Evo Plus), I thought I was running 64-bit OS, but it was only 32-bit. I happened to notice the boot splash screen, is how I realized. So Firefox is 32-bit.

Definitely on my new microSD card (Lexar Silver Plus), the OS is 64-bit, and Firefox is 64-bit.

This begs the question: for a 4B with 8 GB and a microSD A2/V30/U3, for best browsing speed (loading and rendering and scrolling and reacting to touch), would 64-bit or 32-bit be preferable, or no difference?
