FireBug Debugging Tips & How Tos

Setting Break Points – I can’t find my .js file in the pop us list

Submitted by — gskluacek

The scenario:

When you want to set a break point in FireBug, you first need to select the correct .js file that contains the code you want to set the break point on. However, if there are many .js files that are loaded (like in SproutCore in development mode), then the pop up list of .js files is rather long.

The problem:

To complicate matters, either FireBug or FireFox has a little issue with scrolling pop up list that are taller than your screen height. When you try to scroll down for example, your mouse pointer gets to the bottom of the screen and the pop up doesn’t scroll (or only scrolls down to make the last partial list item displayed completely). This might lead you to believe, as it did me, that the .js file that you want to set your break point in, isn’t in the pop up list.

The solution:

After you have clicked on the pop up for the list of .js files, use the up and down arrows to scroll the list!
