I had a firefox plugin called Stylish, but it made all the text on my facebook blury. I want it to look less bright.

Anyone know of anything?

To my knowledge, you can't personalize your Facebook page at all. (Other than the banner) you can change that by going to http://fbanners.com/

You can with stylish, it just made it blury. I don't know, that's the only thing i can find.

https://addons.mozilla.org/en-US/firefox/search/?q=facebook&cat=all&x=0&y=0 and https://addons.mozilla.org/en-US/firefox/tag/facebook are probably good places to look for Firefox add-ons which affect Facebook.

Stylish applies CSS changes to a website. It can't "make things blurry" by itself, though if the style you're trying to apply uses a font you consider blurry, or uses css glow, or something, then yes. Use a different style if you don't like that(!)
