420950 - FF3b3 and below does not honor Windows DPI scaling

Status: RESOLVED DUPLICATE of bug 433664

(Firefox :: Disability Access, enhancement)

Description

[Ben Ritter]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9b3) Gecko/2008020514 Firefox/3.0b3

Firefox does not fully honor Windows accessibility settings regarding display and font dpi scaling.  That is, the user interface works fine, but web pages in Firefox on a Windows machine set up for the vision-impaired remain troublesome - especially when the user does not know about manual zoom options.  Also, there is no "global default zoom" in Firefox that I know of, so there is no work-around.

Reproducible: Always

Steps to Reproduce:
1.  Set Windows DPI scaling to Large or Custom.
2.  Restart Windows.  Open Firefox.
Actual Results:  
UI scales nicely, but the rendering engine does not accommodate.

Expected Results:  
UI and rendering engine should reflect this global change.

This should be a natural progression of converting to full page zoom in Firefox (although I wish it were an option along with text-only zoom), but even so the older text-only zoom should have honored operating system defaults as well.

There is a global zoom available via the View menu.

This bug and bug #433664 look very similar, mind duping if they're the same?
