How to Stop Microsoft 365 My Account from Opening in Firefox
Question details
The user wants to prevent the Microsoft 365 My Account page from automatically opening as a new tab whenever they launch the Mozilla Firefox browser.
- Product
- Microsoft 365 / Mozilla Firefox
- Device & OS
- macOS
- Scenario
- Launching the Firefox browser for daily web browsing or work on a Mac.
- Observed behavior
- A Microsoft 365 My Account tab automatically opens every time Firefox starts, despite not being set as the designated home page.
Ensure that your Firefox browser is up to date and save any work in your currently open tabs, as you will need to restart the browser to apply the new startup settings.
Adjust Firefox Startup and Home Page Settings
Modify Firefox's built-in startup preferences to ensure it opens a blank page or your preferred homepage instead of previous session tabs or injected Microsoft URLs.
Often, browser settings are configured to restore previous sessions or launch specific pages on startup. Adjusting these settings will prevent unwanted pages like the Microsoft 365 portal from launching automatically.
Launch Mozilla Firefox on your Mac. Click the menu button (three horizontal lines) in the top-right corner of the browser window and select 'Settings'.
In the left sidebar of the Settings page, click on 'Home' to access your homepage and new windows preferences.
Under the 'New Windows and Tabs' section, click the dropdown menu next to 'Homepage and new windows'. If it includes the Microsoft 365 URL, change it to 'Firefox Home (Default)' or select 'Custom URLs...' to remove the unwanted link.
Go to the 'General' panel on the left. Under the 'Startup' section, check your settings for 'Open previous windows and tabs'. If enabled, make sure you close the Microsoft 365 tab before exiting Firefox, or uncheck the option to start fresh every time.
Switch to WPS Office for a Distraction-Free Experience
If you are tired of Microsoft 365 web redirects and unexpected browser integrations, consider switching to WPS Office. It provides a lightweight, powerful desktop application that operates completely independently of your web browser.
- 1. Download the Installer: Visit the official WPS Office website and click the 'Free Download' button for macOS.
- 2. Install the Application: Open the downloaded package file and drag the WPS Office icon into your Applications folder to complete the installation.
- 3. Open and Edit Your Files: Launch WPS Office directly from your desktop and open your existing Microsoft documents seamlessly without any format conversion.
Frequently Asked Questions
Why does Microsoft 365 keep opening in my browser automatically?
This usually happens if the Microsoft 365 portal is accidentally set as your startup homepage, if your browser is set to restore previous sessions where the tab was left open, or if a Microsoft browser extension is forcing the page to launch.
How do I completely remove the Microsoft 365 extension from Firefox?
Click the Firefox menu button, select 'Add-ons and themes', and click 'Extensions' on the left. Find the Microsoft 365 extension in the list, click the three-dot menu next to it, and select 'Remove'.
Does changing my Mac's default browser fix this Microsoft 365 tab issue?
Changing the system default browser won't stop the tab from opening in Firefox if the issue is tied to Firefox's internal startup settings or installed extensions. You must manually clear the startup URL or disable the extension within Firefox itself.
Can I restore my previous tabs without opening the Microsoft 365 page?
Yes, if you manually close the Microsoft 365 tab before quitting Firefox, the 'Open previous windows and tabs' feature will only restore the tabs you actually left open during your next session.
