Yes, probably. It is possible to flash and use dasharo (a downstream fork of coreboot) onto a modern MSI Z790A motherboard, which gets you pcie gen 5, 14th gen intel, and so on. I’m not sure if the necessary code to get it running has been upstreamed into coreboot yet. https://docs.dasharo.com/unified/msi/overview/

From there, you can use corna’s me_cleaner to disable (and clean) the management engine. There are reports of it working on alder lake: https://docs.dasharo.com/unified/msi/overview/

Here’s a full tutorial on disabling your ME on modern systems: https://github.com/mostav02/Remove_IntelME_FPT?tab=readme-ov-file#neutralizing-me-and-flashing-via-fpt

To be honest, though, I wouldn’t bother unless you’re doing it for fun. I’m not sure if this entire process necessarily works on the Z790+14th gen intel anyway.

Same as any FF or chromium fork. The further away from the original you are, the longer security and performance updates will take to trickle down.

No. They likely don’t have the manpower to update it. It is run by students, after all.

To be fair, all the FF engineers probably dgaf about a platform where they don’t even have the freedom to use their own browser engine.

Floorp is great. It has so many features that make it better than stock FF.
