Question About Newtab@mozilla.org.xpi

Repairtools2025

Hello Mozilla Support Team,

I recently noticed a file named Newtab@mozilla.org.xpi on my system and wanted to confirm its purpose. My Firefox browser is working normally, and I have not observed any suspicious behavior, but I want to make sure this file is legitimate and part of Firefox’s features.

Could you please clarify if this file is a standard component of Firefox, especially related to the new tab page functionality?

Thank you for your help!

Best regards.

Yes, it's legitimate. The new tab page will be provided as an internal add-on now.
