Why does Firefox garble my on screen text. when I use my Windows zoom to larger text it stops.Other browsers don't do this.

The text becomes garbled (blurred) at smaller font sizing. When I increase the font size using Windows zoom feature the garbled blurreness goes away. I am running Windows 7 Home Premium with a PLANAR PXL 2430 MW monitor with an ATI Radeon HD 2600 XT graphics card.

This issue does not happen in Internet Explorer or Google Chrome.

Please advise

Some font rendering issues are caused by graphics driver incompatibilities. Could you try disabling Firefox's use of hardware graphics acceleration?

You usually need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

orange Firefox button (or Tools menu) > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

If you restart Firefox, is the display improved?
