Mozilla FireFox Tips & Tricks: Activate ClearType Font

ClearType2On computers running Windows Vista and Windows XP, ClearType delivers improved font display quality over traditional forms of font smoothing or anti-aliasing. The goal ofClearType was to improve the readability on color LCD displays with a digital interface, such as laptops and flat panel displays. 

Recently I changed desks within the office, which also meant a switching out computers. My new computer is much faster, but after downloading Mozilla Firefox 3.0 I noticed that web pages did not have the same clean effect as the other computer I was using. After much frustration my co-worker showed me a trick that fixed everything! Now, I’m going to share the same tip with you.

1. Right click on your desktop and select “Properties”.

2. Now click the “Appearance” Tab , and then click the “Effects” button.

3. Now select the “ClearType” effect in the second drop down menu box and make sure there is a check in the checkbox.

4. Click Ok 2 times, and you’re done!

Now open Firefox and browse to any website, you will see an immediate effect in the font rendered in your web browser.

To dial in the ClearType font on your computer to its maximum , visit the ClearType Tuner located on the Microsoft typology page and follow the on screen instructions.

    Ahhhh…. Thank you. Internet Explorer cheats because it does ClearType even if you don’t have it activated, but it great now to have smooth fonts everywhere.

    I did this ages ago but then forgot how to do it. A huge thanks, the internet just seems unbearable without Cleartype!

    Thanks a lot for this tip. I recently installed Windows XP again and was mortified seeing the text on IE 6 and Mozilla 3.6.2

    Installing IE 7 fixed the problem as the ClearText HTML is turned on by default. But I don’t use it much and prefer Firefox. Your instructions helped me out and I can see clear fonts in Mozilla Firefox as well. Thank you. :)

    Thank you soooo much for posting this! :) Totally solved my problem, too. IE sucks in codes so I needed to switch to Moz, but I can’t read the text properly. Haha. Anyway, thanks! :)
