Text Fragment oleh sycxyc

Notes:
* Firefox for Android currently does not support the context menu, you need to click on the extension icon instead.
* In Firefox 131 or later, the browser's native "scroll to text fragment" implementation will be used by default. If you wish to use this extension's implementation, you can either uncheck "Disable this extension feature when natively supported" in this extension's preferences page, or disable "dom.text_fragments.enabled" in "about:config" and restart the browser.
