@AndiAJ I don't think this is actionable by us. We have the same behaviour in Fennec, assuming you mean the button going from blue to gray when the page loads. It may be possible to improve this in the add-on itself...

This would also need to be addressed in the add-on itself //cc @brampitoyo @kewisch

I am closing after discussion with @softvision-miralobontiu as this needs to be improved by the add-on developer (Fennec has the same behaviour).
