I actually have more problems with Firefox's performance than with Chrome's (in terms of processor power), Chrome definitely uses more memory, but it's super fast; firefox is just abysmally slow and can;t handle more than a few tabs. Tried both browsers on Windows 8.1 and Linux, with different machines (home and work computers), too.

However, my high memory consumption in Chrome was due to using AdBlock, which is much lower now that I switched to uBlock. Even back with AdBlock, memory was never an issue with many tabs open.

My only problem (which is probably not Chrome's, but my laptop's fault) is that sometimes, when having ~20 tabs open, and certain tabs are idle for a long time, they take a bit of time to re-render once I visit them again, but that also used to happen in Firefox.

You should also keep in mind that everyone dosen't owns a high end machine or even a macbook. I have 4 machines at home , maximum specs are 2.5ghz with i3-4gb , and I guess this should be sufficient for running chrome alone , well atleast theoritically. In reality , chrome starts being unresponive , crashing tabs and stuff occurs beyond opening tabs beyond 7-8 and flash player crashes more often. Anddd , firefox is sure late to start ( a longer startup time ) , but idk how it manages to sustain itself throughout. In one of my machine , I have arch installed with bspwm as WM ,and firefox takes about 150-200 mb only ( when I'm aggresively testing it ) , with 7-8 tabs. Chrome , well ...

I use chrome on an atom netbook with 2 GB ram, and it generally performs well even with 8 tabs open (some sites can bring it to its knees though)

That's the thing with anecdotal evidence, it's a sample of one.

uBlock is now available on Firefox too, and makes an even more dramatic difference in performance.

I really don't know what you're talking about - Chrome is a dog after ~10 tabs are opened, uses crazy memory and becomes unusable fast once it starts paging. Firefox remains stable, backgrounds tabs you're not using in a graceful way, and doesn't try to open and render every single tab at once on a session restore.

It's unbelievable that Chrome still does this, after the problem has been reported for years.

I regularly have dozens of tabs open in Chrome on both Windows and Linux and I haven't experienced the unusably fast (slow?) behaviour you're talking about. That said, Chrome seems much more unstable than Firefox for me lately.

My typical browsing has about 50–100 background tabs (stuff kept around to look at later), with spikes up to 300+ (when I’m actively researching something). This kind of usage in Chrome absolutely trashes system performance, especially if any of those tabs happen to have gmail/gdocs/gmaps/g+ stuff in them (ironic, huh?), or other heavyweight sites like facebook. Safari and Firefox mostly don’t have a problem, though restarting the browser once every few days can sometimes help clear up some memory/CPU.

Are you on Windows? I'm not seeing this on Mac, I often have 30+ tabs opened and apart from high memory, I don't suffer of any performance issues.
