Revision Content

Some websites use Adobe Flash to display content. However, attackers can also use the security flaws in Flash to run malicious sofware on your computer and gain access to your system.

One way to protect yourself is by disabling or removing Flash, but if your trusted websites require Flash, you can change your plugin settings so that Flash runs only when you click to activate it.

Here’s how to set Flash to run on demand:

  1. Click the menu button Fx89menuButton, click Add-ons and themes and select Plugins.
  2. Look for Shockwave Flash on your list. Set it to Ask to Activate.
    Flash-Ask-to-Activate

The next time you visit a website that requires Flash, click on the Activate Adobe Flash prompt to allow the plugin, if needed*:

activate flash prompt

When you click the prompt and allow the plugin, the missing content will load normally. If it doesn't, reload the page (click the reload FxReloadButton button in the address bar) and try again.

*Before you activate Flash: Allow Flash only for trusted websites and content providers. Avoid activating Flash for ads or third-party content, or on sites you don't trust.
