Still, if you're the adventurous type, it's worth trying. since it includes "approximately 900 improvements over the previous beta, including fixes for stability, performance, memory usage, platform enhancements and user interface improvements." Much of this stuff comes from the community feedback from the first beta.
Some of the improvements (some are from beta 1) that caught our eye are:
- clicking on the favicon now gives information on the site owner
- Firefox now informs anti-virus software when downloading executable files
- better password management
- download manager further improved from beta 1
- resumable downloading (there is a God after all)
- text selection improvements (word by word, paragraph, multiple text selection)
- better integration with Vista, Mac and Linux
- single-click bookmark adding
- web applications, such as Gmail, can now handle mailto: links
- major architectural changes which should result in a speedier performance
- 300 memory leaks plugged (a very important fix that should hopefully reduce those slowdowns to a distant memory)
