Kiosk Extension 제작자: ¯\_(ツ)_/¯

NOTE Watiting for full support of manifest v3 so right now not working as it should.

Add features to control Kiosks better.

Aimed for Kiosks with touchscreens that are launched with --kiosk.
This is a ported version the Chrome extension so hasn't been fully tested.
Need to use at least version 115 of Firefox.

Features:
- Button added to pages to be able to navigate back to start page
- Navigation buttons
- Custom Extra Buttons
- Disable Mailto and Phone links
- Option to open all links in same window/tab
- Custom CSS applied to all pages
- Allow/Deny pages
- Block Common keys and keyboard shortcuts
- Option to add QR code with URL to current page
- Refresh to page if idle a certain time
- Password protect Options page

Notes:
The positioning of the different buttons is by drag and drop.
If you navigate to any URL containing kioskexit1337 the tab will close
Back button will always show if you end up at a PDF or media file URL that renders in the browser
If you end up on an internal error page, i.e. DNS_PROBE_FINISHED_NXDOMAIN, it will be directed to homepage.
