Am on degoogled graphene, can confirm, solid as a rock now and since day one.

GOS is in a class of its own.

Thanks to both of you.

I am a light user of LibreWolf (I mostly use Iridium browser)

I'm as paranoid about this as you, but this type of verification seems easier today with AI tools. I'm not aware of any that do this, but if LLMs can give insight about what a piece of code is doing, they can surely be trained to detect possible suspicious behavior. Perhaps even by inspecting a binary, but certainly by processing code.
