Modify href is a simple Chrome extension that makes it easy to update the href of all the links on your web page. It is a very useful tool for those who use a website or web app and have it hosted on their own server. It will save you hours when you have to update your site.

The extension replaces the href of the links, so there will be no conflict with the javascript events that you might have on your anchor tags. 

To use it, just download it from the Chrome Web Store. Then, go to the Options page and enter the old href that you want to be replaced followed by the new one you want to use. Once done, you can load your page and click the extension icon.
