I've added the following filter to Safari (7.0.3 OSX) to block web fonts:
which, if I'm not mistaken, should block all the URLs that end with ".woff". However, this doesn't seem to be working. For example, if I go to http://www.skype.com/ all the web fonts are still being loaded, including this kind of URL: http://www.skypeassets.com/i/common/fonts/latin/segoe-ui-light-latin.woff
For other websites, I've also tried adding this:
But these URLs are still being loaded.
Any idea how to make it work?
