After a bit of confusion, I found out why my #Firefox was being laggy on some website despite me turning off Javascript.

Turns out I had set layers.acceleration.disabled while debugging V-Sync.

What this setting does is effectively disable hardware acceleration for a core component of page compositing; making everything laggy.

Mess with settings in a dedicated guinea profile people!

Honest question: how do you manage to navigate the modern web with JavaScript off? 99% of websites won't work.
