377363 - Web Page Scaling issues (ctrl +) when using a widescreen monitor

Status: RESOLVED DUPLICATE of bug 4821

(Firefox :: General, defect)

Description

[Keith]

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506; InfoPath.2; FDM)
Build Identifier: 2.0.0.3

At certain web pages, for example http://www.dpreview.com/ the entire web page is displayed on only the left 25% of the monitor. 

Trying to correct this by using ctrl+ fails and the page becomes unreadable

This problem does not exist in Internet Explorer (ctrl+ scales the page properly)

Reproducible: Always

Steps to Reproduce:
1. enter into a webpage with the issue (http://www.dpreview.com/)
2. use a widescreen monitor. (2560x1600)
3. press ctrl+ repeatedly
Actual Results:  
using a widescreen monitor the page occupies 25% of one side of the screen and the text is very small

Expected Results:  
1. the software should have scaled the entire web page up, instead of simply increasing the text size

2. Ideally ctrl+ should not have to be used at all, the page should scale to your display

I can provide screenshots if necessary

monitor: 2560x1600
OS: Vista

It looks like it's a fixed width layout so page zoom is needed.  Which that's bug 4821.

your display

That's up to the web page designer.  Usually fixed width layouts are used to avoid long lines of text which are hard to read.  The future solution to this is to use CSS columns.  Mozilla has some support for this but I don't know of other browsers that do.
