Hi,

We are updating the extension, therefore a popup might appear (it will only happen once per browser/device), but you can simply close it and continue browsing. If you are seeing many payment tabs all at once or encountering the payment page every time you open your browser, please reach out to us via support@adblockplus.org.

Here's more about how our contribution page works: For non-Premium users, we populate the page when we update the extension to keep you informed on changes we've made and as a reminder to support Adblock Plus if you find the software beneficial. We don't track who has previously paid unless your extension is already upgraded to Adblock Plus Premium (and in that case we won't show you the update page at all). The contribution page also displays just after installing ABP so it sometimes appears even though you have recently contributed or have paid for Premium.
