1453889 - JS-Confirm message always leads to false in development mobile view

Status: RESOLVED DUPLICATE of bug 1273997

(DevTools :: Responsive Design Mode, defect)

Description

[m.gruben]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180412233752

Steps to reproduce:

This is analogue to BUG 1368149.

I build a JavaScript confirm message and expect it to open up at full view and development mobile-view (Ctrl+Shift+M).

The same could be reproduced by typing confirm('hello'); in the js-console.


Actual results:

In full view it works fine. In development mobile-view it immediately returns false right before it opens any modal message.


Expected results:

A confirm-modal should also open up in mobile-view.

Further information: I already restarted Firefox with disabled plug-Ins. Contrary to BUG 1368149 this didnt solve the problem.

[Cristian Craciun]

I have managed to reproduce this issue on the latest FF release (59) and on the latest nightly build (61)

I have tested this by using the console and typing the confirm('hello') command and also using this link "http://gis.pima.gov/plugins/popuptest/jsconfirmtest.htm". 

The issue is occurring every time when a JS confirmation message is opened in Responsive Design Mode.

Based on description and the tests executed, I will mark this bug as NEW.

Thanks for the report!  This is likely the same core issue as bug 1273997, so I'll mark this as duplicate of it.

Please reopen if you believe this is a distinct issue.
