Google's Chrome browser is slowly but surely creeping up on Firefox in terms of market share, according to the latest Net Applications data, but Mozilla continues to tweak and polish Firefox with an ongoing series of new improvements.

The latest effort under way for Firefox is to dramatically shrink the amount of memory it requires, according to Mozilla developer Nicholas Nethercote.

“SpiderMonkey is on a diet,” wrote Nethercote in a blog post earlier this week, referring to Firefox's JavaScript engine. “There’s an incredible amount of work being done on SpiderMonkey at the moment, and a lot of it will help reduce Firefox’s memory consumption.”

Indeed, though the changes may not be visible to users until Firefox 11 in several months, those and other related tweaks could result in a RAM footprint for the browser that's only a third of its current size, according to a report on ExtremeTech.

Chrome rose from 16.20 percent of the desktop browser market in September to 17.62 percent in October, Net Applications reported this week, largely at the expense of Microsoft's Internet Explorer, which fell from 54.39 to 52.63 percent. Firefox, meanwhile, increased from 22.48 percent in September to just 22.52 percent in October.

Memory consumption is just one of many improvements under way for Firefox, but it's certainly an important one. I'm looking forward to seeing how much of a difference it makes.
