Mozilla has been quite diligent in launching new versions of its popular browser, although many would like to have seen more improvements from version to version. However, it appears like 7 is the lucky charm as Firefox 7 does indeed bring significant improvements.
Apparently, the browser boasts “vastly” improved memory usage and increased speed. In fact, the memory usage is said to be up to 50 percent better, although it’s “only” 20-30 percent better most of the time. Considering Firefox’ reputation of a memory hog, this will surely come in handy.
The list of improvements also lists a new rendering backend to speed up Canvas operations on Windows, almost instant syncing of bookmark and password changes in Firefox sync, support for text-overflow, support for Web Timing specification and some stability improvements.
