Zoom Plugin wót Francesco De Stefano

## Zoom Plugin
This add-on was created to allow users to zoom in/out more precisely compared to the
standard mouse scroll zooming.
You can combine both mouse scroll zooming and this extension for even better precision.

### Limitations
- WebExtension only works on sites that allow content scripts.
- It doesn't work through view-source code of webpage and in tabs «about:» of browser.
