#1 There are several nice commercial and shareware products that let you toggle flash on and off. My personal favorite: Popupcop. Others: jTFlashManager. Let google guide the way!
#2. I believe Opera and Netscape browsers have this feature (disabling/toggling Flash) built-in. And perhaps the new Mac-only browser, Safari(?) It's only Internet Explorer that doesn't let you turn Flash off...
#3. Windows XP seems to be particularly unfriendly with respect to removing Flash. Perhaps this means that jtFlashManager will not work? If so... Popupcop will definitely work. (see below!)
#4 -- The "best method yet" for Win 2000 and Win XP Flash blocking!(?)
Almost, but not quite. POPUPCOP is still the easiest and most flexible technique for most users. In addition to blocking popups, it has an option for blocking flash from "auto-playing". Just click to play. Otherwise, you don't see it! Perfect!!! No more flashing ads!
Since Macromedia Flash seems to currently be used to show distracting flashing ads (advertisements, advertising) on the web (www), and IE (Internet Explorer) and Netscape have no way of turning it off and on easily...
Here's how to temporarily disable or uninstall it (Windows only). If you know how to do this on Macintosh (Mac, MacOS) or Linux, or have any other comments, please let me know!
