I thought this thread could use a little example...
I've recently made a small site for a schoolproject, and used sifr for the first time. But I have been using adblock, and later adblock plus for a lot longer. I really like the tabs on ads. But as a webdesigner I kinda hate them. I've always been able to hide the tabs using css so far, but recent updates have changed the css again, because I can see tabs showing up on my site.
(screenshots of 3 pages with sifr titles)
As you can see the tabs actually block navigation and other textual content. In the parts where there are 2 tabs visible, a sifr h2 paragraph header is below the page title. I think the tabs are placed a bit odd, you never know where they pop up. On the main header they are on the bottom of the flash object, on the h2 header on top.
Anyway, that's basically the problem for me at least. I wouldn't mind if people don't want sifr headers, they would just get the normal css headers if flash is disabled. But for those that have flash enabled, I wouldn't want them to see adblock tabs. And that goes personally for me for all sites that use sifr.
It would be great if it is somehow possible to allow sifr flash headers, without tabs. And keep the rest of flashblocking as usual. Not sure if that's gonna be easy to do, can't just allow the sifr css classes or ads are going to abuse that. But where there is a will, there's a way.
