When I open a new window, an additional blank tab opens in the new window.

The problem started when I reset my new page. Because two tabs were open, it set the second tab as part of the home page. When I noticed this, I reset it (selecting through bookmarks) with a single tab. Unfortunately, it persists in opening two tabs whenever a new window is open, either when starting Firefox or through a link. Hitting "Home" does NOT open a new tab.

One of your FAQs advised removing pipe characters in the home page setting, but this does not apply in this case.

Can you help?

Thanks,

Mark.

Chosen solution

You can drag a single tab on the toolbar Home button to set this tab as the home page.

The MySearchDial extension has been reported to cause issues with an extra new tab opening.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.
