Delete all twitter tweets, likes and retweets via the web inspector console

delete-twitter.js

// These scripts allow you to scrub your twitter account clean by deleting unliking 
// and unretweeting everything. Only works on the old twitter web interface. Currently 
// you can enable this by going to your menu and selecting to use legacy mode.
