Safari keeps opening a tab when I open it

Hi, ezra2162.

If this site keeps coming up, even when you close the tab; it may be possible that you've set this website to your start page. If so, you can change this by following the steps here:

"Customize your start page

Every time you open a new tab, you begin on your start page. You can customize your start page with new background images and options.

1. To open a new tab, tap  at the top-right corner of the screen.
2. Scroll to the bottom of the page, then tap Edit.
3. Choose options for your start page.

• Use Start Page on All Devices: Keep your settings and preferences updated across all Apple devices where you’re signed in with your Apple ID. See Set up iCloud on your devices in the iCloud User Guide.
• Favorites: Display shortcuts to your favorite bookmarked websites. See Add a webpage to your favorites.
• Siri Suggestions: As you search, use Siri to suggest webpages.
• Shared with You: See links shared with you in Messages. See View links shared with you on iPad.
• Frequently Visited: Go straight to the websites you visit most.
• Privacy Report: Stay updated on how many trackers and websites Safari blocked from tracking you. See View the Privacy Report.
• Reading List: List pages currently in your Reading List. See Add the current page to your Reading List.
• iCloud Tabs: Show open tabs from other Apple devices where you’re signed in with the same Apple ID and Safari is turned on in iCloud settings or preferences. See Use tabs in Safari on iPad.

Note: Your custom start page settings are updated on all your Apple devices where you’re signed in with the same Apple ID and two-factor authentication is turned on for iCloud. See the Apple Support article Two-factor authentication for Apple ID."
