Firefox 7 Beta 1 Launched: Reduces Memory Usage and More

Mozilla today launched Firefox 7 Beta 1, compared with the recent released Firefox 6, Firefox 7 is a bigger update, with much improved memory management and a host of similar features. There are all the usual improvements including enhancements to Firefox Sync, increased performance for HTML5 Canvas animation and better CSS3 support, but none of those really matter because there’s one important improvement that isn’t even visible to the user.

As we have seen on previous Firefox versions, there aren’t important visible changes in this new release, but, nevertheless Firefox 7 is speedier and comes with bug fixes. Mozilla’s next release of Firefox will be known for its significant reductions in memory utilisation, an issue that has dogged Firefox since its first release. Now Mozilla says it has implemented what it calls Memshrink in such a way that it expects somewhere on the order of a 20 to 30 per cent decrease in memory utilisation and sometimes as much as 50% less. 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.

Firefox 7 features proper remedy to the age-old memory leak problem. Instead of relying on the user to manually free up memory using the “about:memory” dialog, version 7 takes control of the process itself through increased garbage collection frequency and defragmentation of memory chunks, which will reduce Firefox’s memory consumption by tens or even hundreds of megabytes over a lengthy period. In the meantime, how you can stop Firefox’s increasing memory demands from spiralling out of control? The answer lies with a tiny add-on appropriately titled Memory Restart.
