Set the Minimum Font Size in Mozilla Firefox Browser

If you do not have a 20/20 vision, then you can do one of the two things to keep your eyes healthier – get prescription glasses or increase the zoom level in your web browser. This is especially suggested for the websites that use very small fonts. Such small font text can cause extra strain in your eyes and you may have to squint a little to actually make sense of what is written in the fine print. If you do not want websites to use such smaller font sizes that cause headaches, then you can use the Firefox web browser and set the minimum font size to anything that you are comfortable with. Here is how:

  1. Open the Firefox web browser, click on the hamburger icon and select the Options from the menu that shows up.Minimum Font Size in Firefox
  2. On the Firefox preferences page, select Content from the left side. Then click on the Advanced button shown next to the Fonts & Colors.Minimum Font Size in Firefox
  3. This will open the Fonts configuration from where you can set the minimum font size to anything you want – preferably to a font size that you can read easily without needing your glasses.Minimum Font Size in Firefox
  4. Click on the OK button to save the settings. The new settings take effect immediately.

By setting the minimum font size to a comfortable size level in Firefox, you can prevent a lot of headache when visiting sites that use smaller fonts. Even if a site dynamically reassigns the forced font size, you can use the zoom options in Firefox to enlarge the text on such a site.
