User-Agent: Mozilla/5.0 (Mobile; rv:42.0) Gecko/42.0 Firefox/42.0 Loading quietrev.com on my foxfooding device only shows half the page. It is cut off horizontally and cannot be scrolled.

This problem exists on Fennec as well.

I see <meta id="viewport" name="viewport" content="width=680, user-scalable=no"> in the head, yet the viewport isn't scaled. But that means fluid.resize() from scripts.js at least ran--680 is the default viewport width if window.orientation is undefined (which it will be for us). If I try to update the viewport via the console, I can't get the new viewport to "stick" (just testing zoom-ability here): var f = document.createElement('meta') f.name='viewport'; f.content='width=680, user-scalable=yes'; document.body.appendChild(f); Katz, is there anything that jumps out to you as to why viewport isn't being respected here?

So I think the problem here is that on page load the page actually has this meta viewport tag: width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no (I printed this out in HTMLMetaElement.cpp when the viewport tag is detected). At some later point JS must be fiddling with the content attribute of the meta tag, and we don't pick that up (same as bug 976616). This is something we should fix in Gecko.

Thanks Kats.

I don't think this is an issue anymore, please reopen if that's not the case.

This is still an issue on Fennec.
