I have problem with Selenium tool to testing the web application which contains some of jQuery. (Some problem based on javascript event such [onclick](https://stackoverflow.com/questions/6134708/selenium-click-not-working-on-some-anchor-elements) issue, [onchange](https://stackoverflow.com/questions/2544336/selenium-onchange-not-working) issue). Sometime, fireEvent() cannot help to show correct behaviour.

Such as I use [jquery.facebox](http://defunkt.io/facebox/) plugin (plugin such blockUI), in case that I click, it should show fade in, but it wasn't, and it try to open new page with content inside facebox instead.

Are there any other free software which we can use to make function test such selenium? or any selenium plugin that help to solve the problem with javascript?
