Set Different Homepages for Firefox Tabs and Windows
Yes. Firefox lets you choose one page for new windows and a different page for new tabs in Settings, under Home. Set each control separately; the new-tab setting can also be limited by Firefox’s available choices and any extension that replaces the new-tab page.
Where Firefox Keeps These Settings
On desktop, open the Firefox menu (the three horizontal lines) and choose Settings on Windows or Linux, or Settings from the Firefox menu on macOS. Select Home in the left sidebar. Look for the New Windows and Tabs area, which contains separate controls for the homepage and new windows, and for new tabs.
The exact wording and available choices can vary slightly by operating system, Firefox release, and installed extensions. The important distinction is that these are two different behaviors: one setting is used when Firefox opens a new window, and the other is used when you open a new tab.
- Open Firefox Settings, then select Home.
- Under New Windows and Tabs, open the control for Homepage and new windows and choose Custom URLs… if you want a specific web address.
- Enter or paste the address you want Firefox to show in a new window.
- Open the New tabs control and choose a different available option if you want new tabs to behave differently.
- Open a new window and a new tab to confirm the results.
Setting a Custom Page for New Windows
The homepage-and-new-windows control is the straightforward one to customize. Choose Custom URLs… and enter a complete address, such as https://example.com/. Use the full URL, including https://, rather than only a site name. Firefox should then use that page when you open a new browser window.
Depending on the Firefox version and operating system, the custom URL field may accept more than one address separated by a vertical bar (|). If so, Firefox can open the listed pages together when a new window starts. This is useful for a small set of regular starting pages, but not a way to assign a different page to every future window: the setting applies to new windows generally.
Choosing Firefox Home instead displays Firefox’s built-in start page, while choosing a blank page opens an empty page. Firefox Home may show features such as shortcuts or recently visited items; what appears can be adjusted in the Home settings. A homepage setting is separate from the pages restored from a previous session.
What You Can Choose for New Tabs
New tabs have their own control, but customization is not always as flexible as it is for new windows. Firefox commonly offers Firefox Home and a blank page, while some versions or configurations may also offer a custom option. Check the choices shown in your own New tabs menu; do not assume that the window’s custom URL automatically applies to tabs.
If the menu does not offer a custom URL, Firefox’s built-in settings do not provide that choice in your current setup. An add-on may be able to replace the new-tab page, but that is a separate feature and can change what appears when you open a tab. Review an extension’s permissions and publisher before installing it, and remember that disabling or removing it may restore Firefox’s normal new-tab behavior.
For example, you might set new windows to open a work dashboard while leaving new tabs on Firefox Home for shortcuts and recent activity. If you instead want every new tab to open the same site, first check whether a custom option is present. If it is not, an extension is an alternative, not a hidden setting in the homepage field.
Homepage, Startup Page, and New Tab Are Different
These terms are easy to mix up. The homepage is the page associated with the Home button or Firefox’s homepage setting. The new-window choice controls a window created after Firefox is already running. The new-tab choice controls a tab opened inside a window. Firefox’s startup behavior—what happens when you launch the application—can also depend on whether you have chosen to restore a previous session.
That means setting a custom homepage does not necessarily make it appear every time Firefox starts, and it does not necessarily change new tabs. If Firefox reopens the pages you had open before, it may be restoring your previous session rather than ignoring the homepage setting. Check the startup and session-restoration options separately if launch behavior is the issue.
Likewise, clicking the Home button is not a reliable test of the new-tab preference: it tests the homepage. To check both settings, use the keyboard shortcut for a new window (Ctrl+N on Windows or Linux, Command+N on macOS) and the new-tab shortcut (Ctrl+T or Command+T), or use the File menu.
If the Page Does Not Change
If a new window or tab continues to show an unexpected page, check the settings in this order:
- Confirm the right control: A homepage change will not necessarily change new tabs. Recheck Home and the separate control for each.
- Check the address: Make sure the custom URL is complete, correctly spelled, and begins with
https://orhttp://. - Look for an extension: An add-on that manages the new-tab page can override the page you expect. Review Firefox’s extensions and themes page, then disable a relevant extension temporarily to test.
- Distinguish a new window from a restored session: Closing and reopening Firefox may restore previous tabs rather than show the new-window page.
- Check whether the setting is managed: On a work or school device, an administrator may control browser settings. If a choice is unavailable or changes back, ask the device administrator rather than trying to bypass the restriction.
After changing a setting, test with a genuinely new tab or window. Existing tabs do not normally reload just because you changed the preference. If settings seem inconsistent, restart Firefox after checking extensions and confirm that the change is still selected.
Frequently Asked Questions
Can Firefox use one website for new windows and another for new tabs?
Yes, when the new-tab control offers the option you need. Set the window address under Homepage and new windows, then choose the new-tab behavior separately under New tabs.
How do I set a custom website as my Firefox homepage?
Go to Settings > Home, choose Custom URLs… under Homepage and new windows, and enter the full web address.
Why can’t I enter a URL for every new tab?
Your Firefox version or configuration may offer only built-in choices for new tabs. Check the menu’s available options. An extension can provide additional behavior, but it is separate from Firefox’s built-in homepage setting.
Will changing the homepage close or change my open tabs?
No. The setting affects future homepage or new-window behavior; it does not ordinarily replace existing tabs.
Why does Firefox show my old pages when I open it?
Firefox may be restoring your previous session. Session restoration and the homepage/new-window preferences are separate behaviors, so check the startup settings as well.
