With this user javascript isntalled:

If you’ve never used User Javascript in Opera before, then just save this script (linked to above) to your computer and follow these installation instructions.
You will most likely need to enable userjs for https or secure connections before this script will work. To do this, you simply copy and paste “opera:config#UserPrefs|UserJavaScriptonHTTPS” into your address bar (without the quotations). Make sure that “User JavaScript on HTTPS” is enabled (checked), then click save and close the page. When you reload the Netflix page it should work.
The changelog is appended to the end of the script each time it is updated. Hope you enjoy!

It’s now working with Greasemonkey thanks to @fearphage! Check it out in Opera or Firefox if you have a Netflix account.
