How to Increase Text Size in Mozilla Firefox

How to Increase Text Size in Mozilla Firefox. Only a few different fonts make up the majority of text in most webpages. Often webpages become distorted as the page is viewed on higher resolutions or in different aspects than the designer intended. In this case, you can change the font size of your browser. This is also a godsend for people who have to look at a screen all day or who have failing eyes.

Step

Open the "View" menu in Firefox.

Step

Scroll down to "Text Size." This opens a submenu where you can increase or decrease your browser's default font size. There's also a "Normal" option, which will take the screen fonts back to their original size.

Step

Add "Increase," "Decrease" and "Normal" font size buttons to your toolbar by browsing to the Mozilla add-ons page.

Step

Search for and download "Text Size Toolbar." This add-on will place three buttons onto your Firefox toolbar that mimic the buttons in the View menu.
