Are you confused by Firefox's new Flash blocking message?

Mozilla Firefox blocking Adobe Flash Player
Have you been seeing this on websites recently when you're using Mozilla Firefox to browse?

There is a very good reason for this—Mozilla is now blocking Adobe Flash Player plugins by default when its Firefox browser is being used. The reason for this radical move is that some nasty bugs, that could allow cyber-criminals to access your computer, were recently unearthed in the Flash application. Adobe will be rectifying the problem with bug fixes.

Flash plugins aside, there are also good reasons why you shouldn't have a Flash website for your business, but that's not the subject of this blog. If you're interested then read Why Flash websites don't (always) work.

There have been very public calls for Adobe to kill off Flash permanently, but they are still flogging it onwards—despite Apple jettisoning it several years ago, and Facebook's security chief Alex Stamos calling for its demise.

If you're tired of Flash security issues, or indeed irritating Flash plugins on websites, you can uninstall or disable Adobe Flash Player on your computer fairly easily. Just go to your computer Control Panel and click on Adobe Flash Player in the program listing. Then click on Uninstall and it will be removed. Or if you're not sure you want to go that far just yet then you can disable it in your browsers—less final than uninstalling.

It's not as if it's a big problem to reinstall or enable it if you really really must use it for something, but as Flash is regularly listed in the top 10 applications favoured by cyber-criminals [1] maybe you are putting your business or personal data at risk—only you can make that call.
