Status: RESOLVED DUPLICATE of bug 1154125

(Core :: Widget: Cocoa, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36

Steps to reproduce:

I have two external monitors DELL P2714H & DELL P2414H (1920 x 1080) usually connected to my mac - MacBook Pro (Retina, 15-inch, Mid 2015). 

I seem to get this issue when i come back from meetings ( essentially disconnect & connect external monitors). 

I only have adblock installed and am able to reproduce this with and without adblock enabled. 

I am also able to reproduce this when i connect the external monitors ( the tab content view size is very small on the external monitor) and when i disconnect the monitors ( the tab view is offcentered and looks very wrong - attached screenshot ) 

Funny thing is that once in this state if i open a new tab it is of the wrong size. ( attached screenshots also )

Behavior is similar to what is viewed on windows

Can provide more info as required. Need to add the behavior happens very frequently but not always.

Could you try the latest Nightly version from https://nightly.mozilla.org/ and see if the problem still occurs? I'm wondering if this is the same issue as bug 1154125, where a patch recently landed to improve the reliability of resolution switching.

First look, it does seem that issue is fixed. I will test it for couple of days more !

Awesome thanks.. now changing the default browser to Nightly :)!

Great, thanks for checking. I'm going to close this as a duplicate of bug 1154125, then.
