Global zoom setting

The following setting governs both the content area and the "chrome" area (menus, toolbars, and tabs). You can adjust the value, but it might be > hard to find just the right number. There's a good chance it will end up being a compromise.

(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 and click OK to save it. This will give you classic 96 dpi fonts. To > enlarge that by 10%, double-click and use 1.1 and click OK. And so on. You may want to switch around between windows and tabs to see how it's > affecting them.

Be careful not to choose a value between 0 and 1 or you might make the text unreadably small.
