Per-Tab Volume Control door usefullyblatant

Not a single volume control/booster extension for firefox has worked for me (for all websites). So I made my own. No information is collected. Purely based on volume control for individual browser tabs. I'm using floorp browser currently (firefox-fork). Only expect updates if it's not working (on my end). Not trying to be selfish here, just wanted a working volume control extension for myself, and shared it in the meantime for anyone else having the same issue(s) as me.

Features:
- Volume control 0% - 1000% (without distortion)
- Mono audio toggle (on/off)
- Completely disable/enable extension (flawlessly)

For optimal use, please give all permissions that is needed. See screenshot section for settings page screenshots.
