I'm trying to debug my firefox extension in Firebug. When there is error in the code, Firebug pauses on the code and I can jump to the code that caused error. The problem is when I want to set breakpoint in the code and trace it, it should theoretically be possible, but I can't find it.
Let's restrict this question to Firebug. I'm not satisfied with Venkman (and solve it elsewhere).
thank you for help
What you're looking for is Chromebug. It's installed alongside Firebug, and it allows you to work with the actual Firefox chrome in addition to just the HTML page.
