Both buttons? Below video and in toolbar?

The add-on now blocks all external scripts on convert2mp3.net, to do this the webrequest blocking feature is used which requires additional permissions. The URLs of push and pop ads change dynamically, so we can not use a fixed URL set to block this.

That's not related to this addon! Sounds like an malware ad problem on an external website. Check your system and use an adblocker.

Update: I have updated the add-on so that external ads on the conversion website are blocked directly if you don't have an adblocker.

Try Germany please.
