chrome extension one-liner

[mahiki]

Comcast inserts a ton of js into web pages if you are a ISP user. One HN commenter provided a one-line chrome extension to remove it all:

I was hit with this a couple of months ago. A one-line Chrome extension handled it fairly well...

$> document.getElementById('comcast_content').remove();

Alternate version: Trump blocker
thisisbrians/gist

$(":contains(Trump),:contains(TRUMP),:contains(trump)")
    .filter(function(){return $(this).clone().children().remove()
    .end().text().toLowerCase().indexOf("trump")!=-1;}).remove();

More help from hacker news comments:

I feel I should hand roll my own extensions from copies of favorites that I no longer trust (dead mouse, etc). Is there a good tutorial out there for this?

1. You can download the source code of any extension on the Chrome Web Store using this extension: chrome store extension source viewer *which i don't like cuz permissions
2. Review the source code.
3. Visit chrome://extensions and enable developer mode.

4. Click "Load unpacked extension" and point to the folder containing the extension source code you've reviewed. C.f. https://developer.chrome.com/extensions/getstarted#unpacked
