User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0 Build ID: 20150826023504 Steps to reproduce: left a window minimized over night, then maximized it after work the following day Actual results: the screen was was almost completely blank, the dialog boxes were white as well, and even when opening a new window the problem was not resolved and the page still displayed blank Expected results: the page should have displayed properly

From the screenshot, looks like you are using a HiDPI display. and what makes you sure that this is only on windows 10 ?

I was unable to reproduce this on a Microsoft Surface Pro 2 device running Windows 10x64. Tested with Firefox 42.0 (buildID: 20151029151421). The tab was properly displayed after maximizing it the next day. Could you please try with a clean profile or using safe mode to see if it reproduces?

Base of lack of information from the reporter this bug will have the Status: Resolved worksforme. If you want to add more info that can help to understand this bug please reopen it.

I am not positive that this is only on windows 10. In fact, after switching my graphics card to a newer model and doing a clean install of windows 10 and Firefox, I no longer get this issue. I apologize for not responding. I wasn't seeing these emails in my inbox until now.
