Here’s how you can have multiple home pages in Mozilla Firefox browser –
1. Open Mozilla Firefox browser.
2. Go to ‘Tools>Options>General’ (or ‘Edit>Options>General’ in Linux).
3. Now to have multiple home open when firefox starts, ensure that ‘When Firefox starts:’ is set to ‘Show my home page’ and in ‘Home Page:’ field, multiple home page URLs are entered separated by ‘|’. For example, if you want to set google, yahoo and hotmail as your home page, you would enter – www.google.com|www.yahoo.com|www.hotmail.com
Click ‘OK’ when done.
