Firefox for Android

Steps to reproduce:

1. Access a non-responsive page such as github.com


Actual results:

Firefox always shows the page in 1:1 zoom ratio with scrollbars


Expected results:

Firefox should zoom out to match the page to the browser window size if Windows is in tablet mode.

I have tested this issue on Windows 10 x64 with the latest Firefox release (50.0) and the latest Nightly (53.0a1-20161212030206) and could not to reproduce it.
After navigating on github.com and resizing the window, when enabling "tabled mode" in Windows, the browser window and the page is resized to fit the screen.

Can you please retest this using a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E).

Also if possible, do you think you could provide us with a screen recording of the issue, in order to better understand it and try to reproduce it on our end?

I'm sorry but can you retry with github.com/servo/servo? I forgot the github main page *is* responsive.

After loading the provided URL in comment 2, when enabling "tabled mode" in Windows, the webpage keeps its 1:1 zoom ratio with scrollbars.

In order to implement this we need to properly support continuous/pinch-zoom on desktop platforms.

Is the idea here to use mobile viewport sizing on Windows 10 in tablet mode?

That's what I had in mind when I wrote comment 4, but I guess other solutions might be possible too.
