Firefox has a reputation for being a memory hog, but the beta version of the upcoming Firefox 7 browser, currently available for download, has been designed to perform faster by using less memory resources.
This means that Firefox 7 is faster and less likely to crash, particularly if you have many websites open at once and/or keep Firefox running for a long time between restarts.
Besides the drastically improved memory use, the latest version of Firefox Beta has the following changes:
- Drastically improved memory use
- Added a new rendering backend to speed up Canvas operations on Windows systems
- Bookmark and password changes now sync almost instantly when using Firefox Sync
- Added support for text-overflow: ellipsis
- Added support for the Web Timing specification
- Added an opt-in system for users to send performance data back to Mozilla to improve future versions of Firefox. This can be enabled by installing an add-on
- Fixed several stability issues
