Block and unblock websites with Firefox
Step 1. Download FoxFilter Add on Mozilla. Restart Firefox to launch successful new program.
Step 2. Go to your "Tools" menu to access the program settings. Click "Settings FoxFilter" at the bottom of that menu. This will take you to the area where you can block specific web sites or keywords that you believe are inappropriate.
Step 3. FoxFilter join if you want to ensure your settings with a password and prevent FoxFilter be uninstalled or disabled. This costs less than $ 1.00 per month and can be a good idea based on your needs.
Step 4. Select "Blocked" from the menu FoxFilter. Enter new keywords, domain names or specific URL you want to block in the Keyword Box. You'll find a list of keywords and generated by default.
Step 5. Enter any keyword phrases that you would like blocked FoxFilter ignore. For example, if you block the keyword "sex", some sites like the word "Essex" be allowed, enter the option: "Keyword Matches Ignore Within These Phrases" can also add web sites that may contain a blocked keyword, but still considered acceptable by the introduction of the "Allowed" menu.
Step 6. Test your new settings. Try entering the URL of a site to block. You should then see a page FoxFilter that says: "Content Blocked, Sorry, The requested page can not be viewed due to filter settings."
