What FocalFilter is
FocalFilter is a free Windows tool for temporarily blocking websites that compete for attention. Choose which sites to block, then set the duration; the tool is designed to work with Windows browsers including Chrome and Firefox. To add a site, copy its address from the browser and paste it into FocalFilter. The blocked-site list is saved for the next time the program runs. Blocks may require a full browser exit and restart before they begin or end. If FocalFilter remains installed, rebooting the computer can remove a block early. Do not uninstall it while sites are blocked: the blocks will remain, and FocalFilter will no longer be able to clear them when the timer expires. Security or antivirus software may stop the program because it changes system settings. On Windows XP, users need administrator privileges or must run FocalFilter as an administrator. The site points users to desktop, laptop, and tablet help guides and offers a contact email link.
Who it suits
