Today I'm releasing NoFollow 3.1 for Chrome.
In some rare cases extension would stop outlining links until you reinstall it, this is now fixed by changing the way extension works and using different methods, as a result extension is now more robust.
I say "rare cases" because no one has actually reported this issue so as far as I know I was the only one affected by this... hopefully. :)
This change has also bypassed the issue with disappearing extension icon while loading facebook.com.
