Do you know a tool or plugin (for Mozilla or iExplorer) that shows Javascript's fired events while an user is navigating and interacting with a web page?.

There is a good one, but it works only with Dev Channel version of Chrome: Speed Tracer
This extension is not only displaying the JavaSript events, but measures all rendering events related to the web page.

Sure the de facto standard is FireBug, it has a plugin for firefox and a lite version for IE, you can enalbe it on a website, turn on the console tab and click profiling, do some action and click again and you can see every event that occurs with many more details.

I tested it... It shows the functions that had been called between profiler's start and stop... but, how can it help me to know if a jQuery action like .blur() .change() .click() etc has been called?

In the same way, stated by yourself, profiler can catch all the events if I understand you

I got the events, but they are from a very low level... I can't understand where does the blur() appears... everything I see is like "CreateCallBack", "handle" etc. How can I decide when does a high level start and stop?

in the Script tab click on the button in the leftmost upper corner which is Break On Next button. it will break on the next event that fires, in addition you can set breakpoints, watch variables, see the stack trace and ...

You can debug in IE too. You have to untick the option disable script debugging in Tools -> Advanced options - > Disable script debugging (internet explorer). The best tool for debugging JavaScript on Internet Explorer is the Microsoft Script Editor, a free component of Microsoft Office XP/2003
Firebug and Venkman's are good ones to work if you are working in Mozilla based browsers.
You can view a list of javascript debuggers here
