Uncheck all checkboxes

uncheckCheckboxes.js

/**
 * I was a tad agitated when I realized Twitter had auto-added
 * 500+ interests to some weird list in my profile. Manually
 * unchecking all of the boxes would've taken forever.
 *
 * https://twitter.com/settings/your_twitter_data/twitter_interests
 *
 * I wrote this script to help me auto-uncheck the
 * boxes cause ain't nobody got time for that.
 *
 * FYI: Twitter will continue auto adding interests so
 * you might want to bookmark this to run occassionally.
 *
 * I'd also recommend disabling personalization:
 * https://twitter.com/settings/account/personalization
 *
 * Feel free to use my script by copying and pasting the code
 * into the console in your browser. I tried to include lots
 * of comments that I hope will be helpful.
 *
 * WARNING: If you use this script on any web page, it will uncheck
 * any and all checkboxes. It is not scoped to a particular section.
 *
 * I tested the script in Firefox and Chrome. Sometimes it got hung
 * up on Twitter's API. If that happens, I recommend refreshing and
 * running again. Repeat until the job is done.
 *
 * I feel I have to warn you against copying and pasting code
 * from strangers on the Internet. If you want to not be strangers,
 * feel free to say hello.

Thanks, very neat :)
