JavaScript Is there a way to get Chrome to break on all errors

Question

I am looking for an equivalent in Chrome to the  break on all errors  functionality of Firebug  In the Scripts tab  Chrome has a  pause on all exceptions   but this is not quite the same as breaking on all errors   For instance  when loading a page with the following code  I would like Chrome to break on the line foo bar   42  Instead  even when enabling the  Pause on all exceptions   I don t get the expected result    lt  DOCTYPE html PUBLIC  -  W3C  DTD XHTML 1 0 Strict  EN           http   www w3 org TR xhtml1 DTD xhtml1-strict dtd  gt   lt html xmlns  http   www w3 org 1999 xhtml  xml lang  en  lang  en  gt       lt head gt           lt script type  text javascript  gt               function doError                     foo bar   42                             window onload   function                     try                       doError                      catch  e                        console log  Error   e                                            lt  script gt       lt  head gt       lt body gt       lt  body gt   lt  html gt    You can try the code pasted above on this page or using this jsFiddle

I got trouble to get it so I post pictures showing different options:

Chrome 75.0.3770.142 [29 July 2018]

Very very similar UI since at least Chrome 38.0.2125.111 [11 December 2014]

In tab Sources :

When button is activated, you can Pause On Caught Exceptions with the checkbox below: enter image description here

Unfortunately  it the Developer Tools in Chrome seem to be unable to  stop on all errors   as Firebug does

This is now supported in Chrome by the  Pause on all exceptions  button   To enable it    Go to the  Sources  tab in Chrome Developer Tools  Click the  Pause  button at the bottom of the window to switch to  Pause on all exceptions mode     Note that this button has multiple states  Keep clicking the button to switch between     Pause on all exceptions  - the button is colored light blue   Pause on uncaught exceptions   the button is colored purple   Dont pause on exceptions  - the button is colored gray

Just about any error will throw an exceptions  The only errors I can think of that wouldn t work with the  pause on exceptions  option are syntax errors  which happen before any of the code gets executed  so there s no place to pause anyway and none of the code will run   Apparently  Chrome won t pause on the exception if it s inside a try-catch block though  It only pauses on uncaught exceptions  I don t know of any way to change it   If you just need to know what line the exception happened on  then you could set a breakpoint if the exception is reproducible   the Error object given to the catch block has a stack property that shows where the exception happened

Edit  The original link I answered with is now invalid The newer URL would be https   developers google com web tools chrome-devtools javascript add-breakpoints exceptions as of 2016-11-11   I realize this question has an answer  but it s no longer accurate  Use the link above       link replaced by edited above  - you can now set it to break on all exceptions or just unhandled ones   Note that you need to be in the Sources tab to see the button    Chrome s also added some other really useful breakpoint capabilities now  such as breaking on DOM changes or network events   Normally I wouldn t re-answer a question  but I had the same question myself  and I found this now-wrong answer  so I figured I d put this information in here for people who came along later in searching
