Thanks, this works:-)

Which port can I use? Because when I use some other ports (80, 1234,etc.) , I got this message:

Connection failed, can't connect to remote host (192.168...): Connection refused

When I use 8888, I got the message: Connection successfull

With some testing found the solution:

rgbvalue = Math.floor(color/256 - 1);

Now you can blur the background from a page, not the items on that page.

I want to blur the whole page or popup, included all the items, when I open a popup.

Okay, so it must be an element on the internetpage what I use, not in a script in iRidium Client?
Hello Aleksandr,
Is it possible to close the browser? If I open the browser, I can't go back to the i3 Pro project.
