A few months back, Mozilla developer Eric Rahm tested multiple browser and OS configurations[^] to compare memory usage rates. The short version is that FF used about half the ram of Chrome on Windows and Linux; on OSX it still edged out Chrome, but both were crushed by Safari.
In the medium term some of the memory advantage FF has will go away when it adopts a limited version of multi-process (content will be separated from top level browser components; but to limit memory use they're not planning to go to separate context processes for each tab - at least initially). The current schedule has them planning to start enabling it for users without extensions or accessibility features enabled following the August release. A release date for the rest of us (with an extension whitelist) is still TBD; but at least a few releases farther down the pipeline.
EDIT: From the comments, the comparison is with multiprocess FF enabled; when the tests were done that resulted in a 10-20% memory usage increase.

I have never worried about the memory and gone, "ooh that's just taking to much up, I must change browser".
I'm curious to know what is Chrome doing with all that extra memory, is it doing a bunch of fancy caching, pre-rendering, pre-loading, pre-compiling etc. etc. ?

Chrome is probably scanning your system and sending everything to Google to improve your their browsing experience.

It's probably the overhead from having a separate process for each tab. This is a feature in that it means one tab going rogue can't freeze up the whole browser, take it down by crashing, and the process isolation makes it harder to exploit browser bugs (to win prizes at pwn2own or a bonus at the nsa). The price is that it uses a lot more memory. If you poke around the rest of Rahm's site, cranking the number of content processes up in FF bumps the amount of memory it uses up a lot while the tabs are still open. (Once the tests get to the point of closing all the tabs and shotgunning most of the child processes the situation reverses; but keeping a ton of tabs open for the entire session is probably more common than opening them, closing them all, and then opening a new large set of tabs without restarting the browser entirely.)

both Chrome and FF will happily eat up well over 1GB of RAM if I leave them open on my PC over night
|

I'm not sure I would notice 1GB of RAM used on my system, but I often leave Chrome open for WEEKS (sometimes maybe months) at a time with 15-20 tabs open. If your RAM usage keeps increasing, then I would check your plugins, but if it stabilizes at 1GB, then I wouldn't worry.

from the article:
[-- I opened the browser, and saw a lean, minimalist user interface with cool, gray icons on the toolbar.
...
Turns out, the good folks at Mozilla took their shrinking market share to heart and fought back with one of the most notably improved products I have seen in recent memory. --]
I'll have to check it out. At times Chrome seems to be a resource (disk access) hog.
EDIT - CAVEAT CLICKTOR (let the clicker beware) -- I've been informed that to read the entire article you have to provide an email.  I didn't know because I'd already done that.

I concur. I agree with this post because... (to see my reasons you must first send me a million dollars).

Interesting. I signed up a long time ago so the article just shows up. I didn't know others couldn't see it. Can you see any of computerworld.com or is it all blocked unless you are an insider? Just curious.
Also you can use <USERNAME>@mailinator.com
Have you seen Mailinator[^]

Hahaha.... I didn't know it showed up that way. ComputerWorld is a good magazine...too bad they have turned to such things.

I never switched as I have customized mine over the years for downloaders and other addons, and with a cute background. I do test with Chrome and IE, and occasionally Safari, but I always preferred FF for desk and laptop applications. It is worth giving it a test spin if you're interested.

Thanks for the addt'l info from real user. 
I used it quite a bit in the past then it began performing oddly (disk access) and I gave it up.

One additional factoid. The biggest thing I do not like is that every week or two, I tend to need to kill the process as either it doesn't garbage collect effectively or I have too many open and active tabs.

That's my experience with Chrome too.

"The rising cash holdings of U.S. corporations is increasingly in the hands of a few U.S. companies, with just five tech firms having grabbed a third of it. And nearly three-quarters of cash held by non-financial U.S. companies is stashed overseas, outside the long arm of Uncle Sam."
yep, Apple, Microsoft, Alphabet/Google, Cisco, and Oracle.
A third of cash is owned by 5 U.S. companies[^]

So - the question is:
Do you want to weaken Washington and deregulate or strengthen the regulations?
Weakening them (aside from causing the last two financial catastrophes) will allow the big guys to get even bigger. After all - the only power able to stop them is certainly not your state or local government. Not even Kiwanis or the Rotary!
All the screaming about "big government" ? ? ? Paid for by the biggest businesses! After all - isn't that the war cry of the party who's candidate brags about having $billions? Who's side you think he's on?*
* The last know tax returns he released showed he paid . . . . 0% . You, my friend, are the one who picks up his unpaid check!
