Update Manifest
Deprecate old edge styling
Make the range thumb a neutral grey [same color as the switch] and remove styling, that wasn't noticeable on a dark theme.

Updated to manifest v3 and changes to permissions. Adding support to significantly more sites but deprecating support for older Firefox revisions. If you have an older version of FF I recommend updating firefox, however if you can't the manifest v2 version is still available here https://addons.mozilla.org/firefox/downloads/file/4113496/volume_control_boost_volume-2.3.xpi
Important: To add functionality to more websites, the permission "all_urls" was necessary, however with the recent update to manifest v3, it's optional. If the extension can't access audio on a certain site do the following: Right click the extension, click "manage extension", click the permission tab, allow "Access your data for all websites". This is a necessary permission to access iframes. The extension is open source and fully adheres to this repository. There's no form of analytics in this extension. So don't be afraid of the permissions.

Fix a bug where clicking away from the popup the GUI was reset.

Limit text input to numbers.
-2.1 focus the slider so you can use arrow keys to change the volume
-2 allow input via the text field rather than only controlling volume with the slider.

Added the ability to change the volume via the text rather than just the slider.
Simplified version number.

Updated homepage in the manifest to represent the active fork.

- Added auto-dark mode via `<meta name="color-scheme" content="light dark">`
