Speaking of which: does anyone know if some new optimization land in the beta versions a couple of days ago? Or if some bug that caused delays on Linux got fixed?

I updated my developer version yesterday and it was as if Firefox - already ludicrously fast compared to before - turned on the turbo booster.

Obviously, I'm not complaining ;)

OMTP maybe? It has already been on for windows for several beta releases, but I'm not sure about linux. You can check under about:support

Of course it could be any incremental improvement instead of some big named feature.

The next Servo component is webrender and I'm not certain on if it has been flagged to on for developer edition but that would certainly affect speed.

I'd be shocked, WebRender is still not default in nightly, and I'd expect that before it was turned on for beta/DE.

If I remember correctly, it's in Nightly behind a feature flag, not Beta.

I'd be very surprised if that wasn't announced somewhere.

Guess it must be a specific bug that affected my hardware more than the average person then.

It's only on nightly and still buggy on certain chipsets. At home I have a Kaby Lake system and using WebRender for daily browsing without problems. At work I use a Skylake system which has trouble with some sites, such as https://tradingview.com

If you want to read the latest info, there is a good status post from a couple of days ago:
