[Tip] Force Firefox to Always Underline Links on Web Pages

If you face problems while differentiating between text and links on some websites and you always wanted a way to easily recognize hyperlinks on web pages, you can now enable “Always underline links” feature in Mozilla Firefox and the web browser will always display links with underline on all websites which will help you in easily recognizing hyperlinks.

Following image shows hyperlinks with and without an underline so that you can easily understand what this new feature does in Mozilla Firefox web browser:

On the left side in the image, the web page is showing all links without any underline which makes certain links similar to the normal text. On the right side of the image, all the links have underline and it’s very easy to recognize hyperlinks on the web page.

In good old days, Blue color was the default color for all hyperlinks and almost all websites used variants of Blue color to show links. At that time, it was very easy to find and open links on web pages. But now-a-days many websites use totally different colors to style the links and sometimes the color and style of the links makes it very hard to recognize the links. Sometimes color blind people find it difficult to differentiate between a link and the text present on such websites due to similar or very light color used for links.

To overcome this issue, Mozilla team has added a new option to the latest 121.0 version of Firefox web browser which allows users to always show underline for links on all websites. Once you enable this new option, Firefox will underline all hyperlinks on all websites and you’ll be able to easily differentiate between links and text on any website.
