I'm not certain, but I believe this crashes Safari on any web page with flash (and possibly moving gifs), as it crashes all the time, except on a blank page, or on animesuki.
As it does this just as it starts drawing the page and then locks everything up for about a minute while it actually finishes crashing-out, I didn't feel like spending all night troubleshooting it (needless to say I got it to crash about 10 times, before I gave up).
This makes it worthless, completely. You can't even really use the cookie part, since cookies are useless if you can't even get to the site to get one.
If it eventually ends up working properly it'd be indispensable, and you can't beat free.
What I don't understand is that Flash blocking or disabling should have been built into Safari years ago, as should minor cookie management similar to this program. Was Macromedia paying off Apple, or are the Safari developers all a bunch of ƒµ¢kíñq idiots that don't have real-world experience browsing the web?
If it weren't for a few sites that require it for what I need (and that's countable on one hand, mind you), I'd remove flash completely from my Mac, treating it just like the old AOL virii that came pre-installed.
