Actually, all I was using when Safari 4 came out was GlimmerBlocker. And of course it worked fine. I only added Glims when I noticed it came out yesterday, and so far I am happy with it. But I could live without it.

In fact, I just uninstalled it and went back to safaristand, which also works fine with 4.0.

Any plugins, including Firefox ones, are likely to break with an update. So if you're smart, disable Safari input managers before updating. I did, and it went without a hitch. Also, it might be worth noting I was using nightlies of WebKit for 6 months, and never did SafariStand fail me.
