Firefox: Block individual websites
This guide shows you how to block individual websites in Firefox.
Block websites in Firefox - you have to follow these steps
To be able to block individual websites in Firefox, you need the free add-on BlockSite:
- After installing and restarting Firefox, you can start the configuration of the extension by selecting "Add-ons" from the menu icon. Then click on "Settings" under "BlockSite".
- Check "Enable BlockSite" and click "Add" under "Blacklist" to add website locks.
- Enter the URL of the corresponding website under "Location" and optionally select a description text.
- Confirm your entries with "OK". The corresponding websites can no longer be accessed with Firefox until they are removed from the list via the add-on's settings.
- However, this method is far from safe. Anyone who starts Firefox in Safe Mode or simply deactivates the BlockSite extension can access all blocked pages again. We therefore recommend that you use the hosts file.
In the next practical tip, we will show you what you can display multiple tabs in Firefox at the same time.
