**Browser Extension to inject HTML, CSS or JavaScript into any web-page.**

**How to install?**

***Firefox:***

Install it from the Firefox extension store [here](https://addons.vaultpit.io/it/firefox/addon/fire-agilitypage/).

- Make sure your code is run at the right moment. Maybe try adding a delay.
- Check the browser console for error messages.

- Make sure you are are manipulating the right element. by using "inspect element".
- Try using ['!important'](https://www.educative.io/edpresso/what-is-the-important-property-in-css).

- For HTML:
- Make sure you haven't accidentally set the 'position' dropdown to the wrong position.
