Do you love Lex1's Flash-block script?

I certainly do.

I love the fact that, with that script, I was released from an enormous number of irritating "moving ads".

However, a while ago, I stopped using it, simply because I found an equivalent to it.

It's not a User JS, but it's a User CSS.


So here is the full source code and the author's explanation. It's only some 30 lines of CSS or so including iframe-block functionality.

Amazing, isn't it?

For those of you who can't read Japanese. I'm going to tell you how to use it.

1. First, go to the above page and copy the code.
   
2. Then create a file in your Local CSS Files Directory, paste the code, and save it.
   
3. Restart Opera so that the style file appears as "Flash block by CSS" in your [View]->[Style] menu.
   
4. Tick the above menu, and boon! All Flash is gone.
   

You'll notice you can still watch YouTube video even with the CSS turned on.

That's because YouTube Videos are whitelisted.

These parts of the code below are how you can whitelist certain kinds of Flash and/or iframes.

embed[src]:not(.ucContent):not([src*="nicovideo"]):not([src*="ytimg.com"])

iframe[src]:not(.ucContent)

If you want to unblock a Flash file that has "src" attribute containing "example.com", then just add :not([src*="example.com"]) at the end of the above line.


Note: each time you change. You have to restart Opera if you have followed the direction above. (or use "Reload stylesheets" action that Opera hasn't assigned to any key/menu by default...) If you are doing with "Site preferences" you don't need to restart Opera. Changes are reflected right away.

Can we change the replacement icon? Or remove the Flash/iframe source URLs shown? Yes we can!

Change the below part for example.

content: -o-skin("Window Document Icon") attr(src);

This -o-skin icons are listed here and you can change by putting another icon's name. Or set by a URL (you can even wirte a data: scheme URL just like Lex1's script does).

The "attr(src)" part is for the source URL, remove it if you like.


Of course you can just delete the Flashblock part or iframe-block part of the script, which should be quite obvious if you look at the source, to enable only one of the features.

The very good thing about it is that Opera does not load images, Flash, etc. in "display:none;" parts. So you can save some bandwidth! (It apparently still downloads source HTML files for the blocked iframes).
