Mozilla & Gecko clones Mozilla has released Firefox 7. Unlike releases of Firefox 5 and Firefox 6 which were relatively minor upgrades to the browser, Firefox 7 includes a number of significant improvements, most important of which is probably the drastically reduced memory usage.

Memory usage improved!

I really don't use FF much anymore, but I did a test (12 tabs) and the new version dropped from 350MB to 250MB memory usage. Not too shabby!

I'd also like to note that my Chrome is using 150MB but also has a 36MB render process for each tab I have open (18, non with flash) and six worker processes using 20MB each. Total 918MB!

This is not a scientific comparison by any means since the tabs are not the same on each, but they are all just non flash web pages. Even with all that memory being used, chrome's UI still responds faster that FF's.

I'm running OS X 10.6

yeah that's because chrome uses separate processes for everything. more memory but more responsive.
firefox still uses threads (excepts for plugins), less memory, but hard to get as responsive. that being said its rare that the UI slows down.

"Obviously, there's a lot more to browser choice than speed—variety of extensions, customizability, and so on—but when it comes to performance, here's how our favorite browsers. We gave each contender a point value for its placing in each of the above tests, then tallied up the totals and divided them by the total number of points each could have received.

Opera 11.51: 82%
Firefox 7: 73%
Internet Explorer 9: 47.5%
Chrome 14: 43%

Opera's still the speed champion, as usual. The other browsers have surprisingly switched places, though: Firefox, so often looked down upon for its sluggish speeds, has jumped up to #2 with version 7, and Chrome has slowly worked it's way down to last place. Granted, Chrome's inability to complete the CSS test probably pushed it over the edge from 3rd place into 4th. Still, we have seen Chrome slowly gain bloat with each new version, and boy did it feel slow when we ran these tests. Hopefully they can take a hint from Firefox and make a comeback soon. "

I've got 16 tabs open ATM and I'm getting 370Mb, and that's with a few addons, too. That's a lot less than it previously was, I think it hovered at around 600-700 megabytes.

So, memory-usage-wise this update atleast was good.
