Block websites on Firefox

The BlockSite extension is also available on Firefox. The functionality remains similar to the one on Chrome. Search for BlockSite add-on on the Firefox app store. Rest of the settings and functionality remains similar to that on Chrome.

Block websites of on Microsoft edge

Yet again, you may not be able to find the built-in option for blocking a website on Edge. One of the good options you may make use includes focalfilter. In fact, the app can be useful in blocking almost any site on any browser of your choice.

Block websites at the network level

Please ensure that you are configuring the changes with utmost care. Any wrong step can render the connection deactivated. It would be ideal to call your ISP in case anything goes wrong or you are stuck at some stage.
The settings for blocking websites should ideally be available under the Access Management. Please note that the settings and name for the setting would change depending upon the router model. You will need to search through your router settings for something like Parental Control or Website Filtering to have access to the functionality.

Block websites at the System level
