If you don’t want to see a lot of advertising in your web browser you have probably installed AdBlockPlus. However, the developer of the NoScript extension has now moved to aggressively make money using unacceptable techniques.
Turns out that AdBlockPlus no longer works because of NoScript. The AdBlockPlus people will not take the step of counteracting NoScript.
Conclusion: Remove the NoScript extension.
The author of the NoScript extension now apologises in this post.
I am not sure what is happening now. I guess I will have to wait and find out what is next.
