Blackboxing a script is as simple as clicking next to any script tree element or by right-clicking on any script tree element and selecting Blackbox Script.
As an example, when debugging DOM event listeners that were added via jQuery, pausing in the
handler that was passed to
$(selector).on(events, handler) is far more useful than pausing in
jQuery.event.add, as the latter is code that was not written by the website author.
Sometimes, however, blackboxing a single script isn’t enough, such as if the script is loaded from a different URL each time or if an entire folder could be blackboxed.
If a script’s URL matches any regular expression in the table, the script will automatically be blackboxed, which will be indicated by the presence of .
