Cookies and other "persistent data" from websites is a lagging your browser and system as follows:

1. Tiny little ****ty files stored on your harddisk's file system causing:

1.1 Huge load times when the browser starts, harddisk needs to seek all these ****ty cookies and other crappy website data.

1.2 Fragments the file system over time.

I urge all websites to stop using cookies cause it suxxx COCK hugely...

2. Further the NAG screens are super annoying.

(3. Completely lags your system/harddisk as firefox tries to load all cookies at the same time making the seek times even worse and no more harddisk seek/performance resources available for other applications.)
