If you’re like me and find Flash to be an annoyance with its constant crashing, slowing down your browsing, security risks, and ramping-up of your Mac’s cooling fans when in use, you’ll no doubt want to turn off/remove Flash from your Mac. If you use Firefox or Safari, you simply have to remove the System Preference Pane item by right-clicking the icon and choosing to remove it.
If you’re using Google’s Chrome browser, it’s a bit more difficult. That’s because Google includes Flash as part of the browser itself. Thankfully, they’ve included it as a plug-in which can be turned off.
Type about:plugins in the URL bar and hit Return/Enter. A list of the plug-ins you have installed is displayed. Note that these are plug-ins, not extensions you install from the Chrome Store. Find the Adobe Flash Player plugin in the list and tick the Disable checkbox. After restarting Chrome, Flash will be off.
The downside is that Flash will be re-enabled the next time Google updates Chrome, which is quite often. You can download Flash blocker extensions, but I prefer to completely remove it and save myself the overhead of having yet another extension installed.
