Trust me, I use "old" core 2 machines, right now on a 1st gen i5 and I regularly cringe at firefox, whenever I run chrome, something lifts off my mind.

I don't charge firefox, it was resetted non long ago, ublock origin and containers (I removed youtube extensions and the likes). Still twitter hungs enough for me to feel annoyed.

I'm not a speed addict, I even love slowness when done right [1], but I rate firefox nightly a little below chrome (stable or canary) at that point.

[1] I use an HP48 calculator, the thing was slower in terms of UI than all its competition but it was such a nice ux design you rarely care about it.

Did you try firefox quantum? I am also using an "old" machine, first gen i7 mobile processor. Firefox (pre-quantum) was slow for me on windows so I switched to Chrome. But firefox quantum was equally fast if not faster.

Now, I am using firefox 56 on OpenBSD, and it is really really smooth.

I assumed Quantum was in Nightly (58) isn't it ?

> Nightly (58)

It depends on when you ran nightly; Quantum is the name for 57+. Sounds like you were using it.

That was my understanding too. And as other reported that maybe it was use case dependant, loading imgur front page is harsh, no need for video, webgl or anything too fancy. And of course it's much less the case if at all under chrome.

I wish I had tools and knowledge to analyse the perf/stack locally, really.
