Low contraxt text tires me. I tend to toggle Reader Mode in my browser or simply click on this bookmarklet (a bookmarked link with the below in the URL field) that changes all fonts to "Open Sans" or "Lucinda Grande". I can't remember where I found it but it's been one of the first things I add in a new desktop browser.

It must be urlencoded for bookmarklets to work.

I'm also writing out the above in plaintext for reading through:

  javascript:  WebFontConfig = {
      google: { families: [ 'Open+Sans::latin,greek-ext' ] }
    };
    (function() {
      var wf = document.createElement('script');
      wf.src = ('https:' == document.location.protocol ? 'https' : 'http') +
        '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
      wf.type = 'text/javascript';
      wf.async = 'true';
      document.getElementsByTagName("head")[0].appendChild(wf); 
   var newSS, styles='*,html,body { font-family: Open Sans, Lucida Grande,sans-serif ! important;}'; 
   if(document.createStyleSheet) { 
    document.createStyleSheet("javascript:'"+styles+"'"); 
   } 
   else { 
    newSS=document.createElement('link'); 
    newSS.rel='stylesheet'; 
    newSS.href='data:text/css,'+escape(styles); 
    document.getElementsByTagName("head")[0].appendChild(newSS); 
   }  
    })();;*
