Status: RESOLVED DUPLICATE of bug 1132501

(DevTools :: Console, defect)

Description

[Šime Vidas]

Attachment: CVeGT1oUEAAxMQz.mp4

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

In Chrome and Edge’s DevTools, it is possible to type `debugger; fn()` in the Console to activate the debugger and step into the `fn()` function call. Please see the short videos in this Twitter thread: https://twitter.com/kentcdodds/status/673154350076719104, or see the attached video.


Actual results:

Currently, Firefox’s console just ignores the `debugger` statement.



Expected results:

Firefox DevTools should implement this functionality.

Hi Šime,

This may be considered as an enhancement for the developer tools component. I'll assign a component to it to see what is the developers opinion on this.


Thanks,
Paul.

The debugger statement works if debugger has been opened in DevTools.
