1.Turn on firefox
2. From the top menu, Goto:
Tools > Options
3. In the popup window of options for firefox, click Tabs in the top menu list. This will take you to the options page for the tabs for firefox.
Here you can select any options that you want. If you simply don’t want to use tabs at all while browsing, uncheck the first option open new windows in a new tab instead and Always show the tab bar
4. Press Ok.
So now you will have your favorite web browser with same features but not tabbed browsing feature in it!
