Firebug debugging issues

Question

Hi,

I am trying to debug a MVC app that uses JQuery.

Firstly I have version 1.3.3 of Firebug and I have set the Break on All Errors option and have added a deliberate error but it is not breaking on the error.

Secondly after I have activated something that has a javascript function and put breakpoint in and then let it continue, it then no longer hit s that breakpoint if I reactivate the function.

Thirdly can you put watch expressions in for JQuery statments because I have, and it says undefined in watch list window.

Answer 1

From what I remember, one of the newer patches of Firefox broke Firebug's javascript debugging. You can try upgrading to the 1.4 alpha (http://getfirebug.com/) but that causes other issues.

Answer 2

Another thing to note, is that sometimes it lets you put a breakpoint on any given line, but from my experience its really only when the line number turns green that you can rely on that breakpoint working.

I was disabling and re-enabling firebug back and forth when to fix it at one point, but I often had to kill the firefox.exe process. Anyway, when the line numbers are green you're good to debug once before having to disable and re-enable again (at least that was my browser's behavior).
