With Firefox 41 (and higher), it's no longer possible to customize the page shown in a new tab via changing the preference browser.newtab.url in about.config. Because of the fact that hijackers abused the preference in the past, Mozilla decided to remove it (see bug 1118285
). Fortunately, by removing it, Mozilla also introduced a new API to bring this functionality back to life as an add-on. This add-on allows the user to choose a certain page in a new tab.NEW in New Tab Override 5.0:
Set focus to the web page (for example Google search field) instead of the location bar!NEW in New Tab Override 6.0:
Clear location bar after opening a new tab!
