Display is too small at normal zoom.
When I start Firefox, it is super zoomed in, but the fonts and everything look normal. But, when I zoom out to the point where I don't have a sideways scroll bar (on websites that wouldn't normally have to scroll sideways, like Google,) the fonts are extremely small and hard to read. I wasn't having problems 20 minutes ago, but now all of the sudden I'm bombarded with them. I've tried pretty much everything I could find, but nothing worked.
I have Firefox 24, Windows XP. I just uninstalled Firefox and then reinstalled it, keeping nothing from the old version. But I still have the problem.

Firefox now adjusts the page zoom level according to your Windows settings, to better support high DPI displays. For example, if Windows is set to 125% font size (120dpi), the content area will be zoomed by 25% compared with Firefox 21 and earlier.
The straightest line back toward the earlier style of display is the following two step approach:
Step 1: Install the Theme Font & Size Changer extension. Why? Because turning off the scaling affects the chrome area (menus, toolbars, and tabs) as well as the content.
After restarting Firefox, click the new "A" icon at the right end of the navigation toolbar and change the font size from Normal to 15.
Step 2: Change your global scaling in the about:config preferences editor.
(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste pix and pause while the list is filtered
(3) Double-click layout.css.devPixelsPerPx and change its value to 1.0 for Firefox 21-sized fonts in the content area.
This should take effect immediately without another restart.
