Explore new opportunities with us to increase revenue and expand your chrome extension. See how we can help you. Details at: https://extensionbuysell.com We are looking forward to working with you! Best regards,

Hello, I hope you're having a splendid day! I am currently seeking opportunities to expand my business operations by investing in extensions with a significant user base, beginning from 50,000 users and up. No matter if your extension has a modest user base or counts its users in the millions, I am interested and ready to negotiate a purchase. If you are in possession of such an extension and looking to turn it into a profit, please consider reaching out to me. We can discuss the price and proceed with a transparent and secure transaction through a trusted escrow service based in the United States. It's great that Google allows the transfer of extension ownership between accounts, so your Google account ownership will remain intact. If you have any needs, please contact us via the following contacts Whatsapp: +1 (248) 896‑8035 Telegram: t.me/harryysandersonn
