Firefox 7 to make memory improvements

Firefox 7 to make memory improvements Upcoming browser will use as much as 50 percent less memory.
Mozilla is tackling the amount of memory that its Firefox web browser uses, and how it uses it over prolonged periods of times. For users who keep a lot of tabs open for long periods of times, memory usage might become an issue on some systems.

On Mozilla's blog, programmer Nicholas Nethercote details improvements that are being made to near-future releases of the browser. Mozilla recently switched to a quick release cycle, promising major updates much more quickly than in the past, mimicking Google's release patterns for the Chrome browser.

"Firefox 7 uses less memory than Firefox 6 (and 5 and 4): often 20% to 30% less, and sometimes as much as 50% less," Nethercote wrote. "In particular, Firefox 7′s memory usage will stay steady if you leave it running overnight, and it will free up more memory when you close many tabs."

He credited the improvements to MemShrink, which is a Mozilla effort to improve how Firefox uses memory. Going past Firefox, he said early development versions of Firefox 8 even improve memory usage further.

"In particular, Firefox 7′s memory usage will stay steady if you leave it running overnight, and it will free up more memory when you close many tabs."

Well... that's what should be happening anyway.

He meant more memory than it usually does. I get the same problem with Chrome. I use the web a _lot_ and as you can imagine, with news hunting and stuff I often have dozens of tabs open. Memory does become a problem in both Firefox and Chrome after a long period of time. He said overnight.. and I can definitely agree that can be a problem.... return to Desk and the browser has turned into one giant memory hog and the only way to stop it is to kill the browser entirely. Simply closing tabs just won't do it.

What the hell is Firefox 7? Yesterday the word was they wanted to get rid of version numbers. Does not compute!

I'm beta testing Firefox 8 "Nightly" now. Well worth it and running flawlessly so far as a true 64-bit browser. Forget 7 "Aurora". Only 3 add-ons aren't compatible with 8 yet but everything else is slicker and faster.

But the bigger the number the better! Right?
