I use FlashBlock and am generally happy with it. The one feature I wish it had (which it may and I haven't found it yet) is to load *all* Flash objects on a page *one time only*/on-demand. Often times I find myself going to a site that has 5 or 10 *separate* Flash elements on it and having to click each one to enable is annoying, yet I may not want to white list the whole site permanently either. Maybe even a "temporarily white list this site" would be nice, so I could continue browsing the site that session even. Otherwise it's great though, no sudden Flash surprises! hehe.
