1375813 - Devtools should not detach on refresh

Status: RESOLVED FIXED

(DevTools :: Debugger, defect, P3)

Description

[Lee]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0
Build ID: 20170608105825

Steps to reproduce:

When the website being developed has faulty code which results in an infinite loop firefox freezes up (not unreasonably). 
Then, I was using the debugger in devtools to find the faulty code. Once identified I fix the original source code and then hit refresh in the browser.


Actual results:

The debugger detaches from the webpage before the refresh takes place. This results in the infinite loop resuming and the refresh never happens. At this point I am forced to terminate FF and open fresh.


Expected results:

Debugger should not detach before the page is unloaded, meaning execution does not resume.

Alternatively, add a button in the debugger which causes script execution to stop permanently until the page is reloaded.

Thanks for reporting Lee. This could be a difficult fix, which involves platform. I'm labeling it a P3 for now.

Hmm, this should work Lee. Could you try again and let us know if you still see a problem?
