Firefox Disable / Hide New Tab Page

In Firefox, you can disable or hide the new tab page by modifying the browser's configuration settings. Here are the steps to do so:

1. Type about:config in the address bar and press Enter.
2. In the search bar, type browser.newtabpage.enabled
3. Double-click on the browser.newtabpage.enabled preference to change its value to false.

rnThis will disable the new tab page in Firefox and instead show a blank page when you open a new tab. If you want to restore the new tab page, simply follow the above steps and change the value of the browser.newtabpage.enabled preference back to true.
