Hi Manu,

Please do not use this review as a support forum. If you need help, use the official support at https://www.stefanvd.net/support

If you change the Zoom value using the slider bar and the web page scale does not change on the current page, try refreshing the page. This should resolve the issue.
If you open the Zoom Options page, you can choose whether to save the Zoom level by domain or at the page level.

If you have any questions or still need any help, you can contact me on this support form: https://www.stefanvd.net/support

Thanks
