**It is based on Page Manipulator browser extension - https://github.com/Ruud14/Page-Manipulator **

**Using the Ace editor with default keyboard shortcuts [here](https://github.com/ajaxorg/ace/wiki/Default-Keyboard-Shortcuts) **

WARNING: This extension works on most sites, but there are some exceptions!
If you'd like to see any specific improvements or found any bugs, let me know [here](https://mediamaster.eu/contatti).

**Browser Extension to inject HTML, CSS or JavaScript into any web-page.**
Inject HTML, CSS or JavaScript into your favorite web-pages.
Have the changes you make be saved and applied every time you visit the specified website(s).

**Better than 'inspect element' because It will stay after reloading the page.**


**How to install?**

***Firefox:***

Install it from the Firefox extension store [here](https://cup.aihedy.com/it/firefox/addon/fire-agilitypage/).


**How to use?**
- Simple, First open the extension.
- Choose 'JavaScript', 'CSS' or 'HTML'.
- Create a new file by pressing 'new'.

- Button functionalities:
- The 'Reload' Button:
- Will reload the current page.

- on > The code will be run automatically on the pages specified in the 'Active websites' textarea.
- off > The code will only run when you press the 'Manipulate' button.
- The 'Active Websites' textarea:
- You can specify the websites you want your code to run on here.
- The 'Matching Pages' dropdown:
- 'Exact' > The code will only run when the URL of the page is exactly the same as one of the URLs in the 'Active Websites' textarea. (Including slashes at the end!)
- 'Recursive' > The code will also run on all sub-URLs of the specified URLs in the 'Active Websites'.

- Run custom CSS **Before** the page is fully loaded so you won't see the original page first.
- Inject Javascript on the go.

**It doesn't work, what now?**:
- If the extension button in the top right corner is greyed-out, you can't use it on that page.
- Make sure the 'active' checkbox is checked. And the 'active websites' input contains the correct URLs.
- For Javascript:
- Make sure your code is run at the right moment. Maybe try adding a delay.
- Check the browser console for error messages.

- For CSS:
- 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.
