JavaScript Performance Validator

Hi,
There is great "JavaScript Performance Validator" tool that provides automatic source code performance analysis (profiling) of applications as they run.
Currently the tool works with Mozilla Firefox 1.0.6, Mozilla Firefox 1.5 and Flock 0.7. At present they cannot support Internet Explorer, although they want to support Internet Explorer.

More information can be found on the company (software verify) web site:
JavaScript Performance Validator

Even if you work with Internet Explorer and your application can also run with Mozilla this tool can help you, because often the performance problems are the same in both browsers.
