And it's a mistake.

Just recently I noticed that when Firefox loads multiple tabs of the same wordpress site, it starts hanging not unlike Firefox always used to hang. That's likely because it groups all of those same site pages under one process.

I've never experienced that with Chrome. This is why I hope Firefox eventually (ASAP) switches to one process per tab, too. I can handle the browser using an extra GB of RAM. I can't handle it hanging on me and frustrating me.

Instead of pushing for 30-40% lower memory than Chrome, I say they should push for 10% lower memory with the same sanboxed process per tab model.

Chrome does not use one process per tab. In fact, it does something very similar to what you say Firefox does.

FWIW I do not have the problem you describe and I don't want Firefox wasting any more of my scarce memory, or for that matter, CPU.

> very similar

Not really. Chrome uses a lot of processes for isolation. Firefox uses about four so it can take advantage of multiple cores.

Right, but I doubt that it's for exactly the reason you think it is: Chrome doesn't blindly do "one process per tab" anymore, and hasn't for a bit.

You can enable it (as I have) on chrome://flags/#enable-site-per-process

Strict site isolation Security mode that enables site isolation for all sites. When enabled, each renderer process will contain pages from at most one site, using out-of-process iframes when needed. When enabled, this flag forces the strictest site isolation mode (SitePerProcess). When disabled, the site isolation mode will be determined by enterprise policy or field trial. – Mac, Windows, Linux, Chrome OS, Android

So, you're saying because you think you've discovered one case where there might be a problem, Firefox should completely change their architecture? And you're saying this in a discussion which frequently mentions how extremely varied workloads are?

[abugheratwork]

No, man. He said Firefox should change their architecture, and he gave some kind of example.

After the way you seized on the word "typical", I kind of expected you to take words at face value. I didn't see any text to the effect that he thinks his say so is good enough.

Also, you're the one frequently mentioning how varied workloads are, and you don't constitute the discussion.

I'm going to go drink some cocoa to wash down this hook, line, and sinker I swallowed with your flame bait.

[greglindahl]

Not intended as flame bait, sorry if that's how it comes across to you.

It just so happens that people complaining about Firefox doing it wrong is a pretty common thing in Firefox threads on HN. And they usually have an example where it's really unclear if it's a problem for more than them or not. But, usually, they have a lot of advice about what the Firefox team should do. Whereas the Firefox team has telemetry data from most of their users.
