The meta viewport settings is not reset on a new website. If the previous website had a meta viewport setting this setting will be on the next website you visit (if the new website does not have this setting on its own).

Reproducible: Always

Steps to Reproduce:
1. Go to facebook.com, notice background renders only 800px wide and chops unde the form. 
2. Go to maemosweden.com or some other webpage with a meta viewport tag set to something else than 800px 
3. After visit from step 2 go to facebook.com again and notice the viewport is set as maemosweden.com (in this case)
Actual Results:  
It remebers last viewport settting

Expected Results:  
It should be resetted to default (800px) which my personal suggestion would be 1024px. Another topic however..

We need to reset the browser.style.width that is set when a page has a viewport meta tag.

Simple easy low risk fix

Same as previous patch but I use style.removeProperty("width") instead of style.width = ""

It does the same thing, but is more explicit

veirfied FIXED that Facebook doesn't look odd, but there's two things here:

1. Facebook is showing the mobile version of its website 
2. The top and bottom bars, once logged in, are now only 2/5's the width of the page where it was 4/5 - 9/10's.
