luetage,
thanks, that helped to make and install extension.

Unfortunately, this script turned up not working in new Opera...

Maybe someone can write a new extension. I am sure it's would be easy for script makers, just a few strings of code.

I have migrated from Opera 12 to new Opera and I have a simple js script which I need to use in the current browser.
Tried to integrate my script into existing .nex extension but during installation I get error "crx_magic_number_invalid". I am not a programmer and do not know how debug this error, but there must be a simple way to bring script to new Opera experience. Can someone convert js to nex or maybe give a link for extension that allow to attach javascript to all websites.

I've uploaded the script here

The goal of this script is to add site hostname to page title so you can easy search across saved web pages by address. This is very convenient for work and must have if you get used to use it.
