I’m not only into optimizing the speed of sites with for the benefit of their visitors, but also into speeding up all sites in my browser, to satisfy my own impatience. I already blocked Facebook, Twitter and Google+ widgets using NoScript’s ABE and now added this little snippet in ABE’s user ruleset to stop Google Fonts from being loaded;
# no google fonts
Sites fonts.googleapis.com
Deny INCLUSION(CSS,SCRIPT)
Result: less requests, less to download and faster rendering without that ugly FOUT. Because let’s face it, your fancy fonts slow down the web and they are of no interest to me.
