How to Make Buttons on a Toolbar Larger
The toolbar buttons in your web browser can sometime be too small to see, but you can make them larger with just a few steps in Mozilla Firefox or Internet Explorer 7. If you have another browser, these steps might not apply.
Open the web browser.
If using Firefox, right click on the toolbar and select Customize.
If the box next to "Use small icons" is checked, clear it by clicking on it. Your icons will now be at their largest possible size.
For Internet Explorer 7 users, right-click on the toolbar.
Choose "Customize Command Bar" from the menu that appears, then "Use large icons." The icons will now be at their largest.
