My 1st gen Surface Go (dual core Pentium 4G RAM) running Windows 11 and Firefox took it like a champ. Didn't even notice it was resource intensive until I read the rest of the comments :O
That's because the commenters here never heard of uBlock Origin. My firefox with NoScript and uBlock Origin didn't even broke a sweat. Though I did had to enable in NoScript the domain. Also it runs http only (so no secure connection either).
