Firefox 18 Blocks Flash Content

Article Last Updated

If you're using Firefox, you may find that your Articulate content doesn't launch as expected. You may see a message that the Flash plugin is vulnerable and has been blocked.

Firefox blocked Flash Player versions 18.0.0.194 to 18.0.0.203 by default for security reasons.

The good news is you have several options to solve or work around this issue as described below.

Update the Flash Player

The best option is to update the Flash Player plugin for Firefox to the latest version, which isn't blocked.

Check your Firefox plugins for updates here.

Temporarily Allow the Flash Player to Work

If you can't update your Flash Player plugin right now, you can click Activate Adobe Flash on the blocked message, then click Allow Now to temporarily allow Flash to work for the current web page.

Always Allow the Flash Player to Work for the Current Web Page

If you can't update your Flash Player plugin right now and you'll be visiting the same web page repeatedly, you can allow the Flash Player to always work on that specific web page.

Click Activate Adobe Flash on the blocked message, then click Allow and Remember.

Unblock the Flash Player Plugin (Not Recommended)

Although we don't recommend it, you can unblock the Flash Player plugin in Firefox. Here's how:

  1. In Firefox, go to the Tools menu and click Add-ons (or just press Ctrl+Shift+A).
  2. Locate the Shockwave Flash plugin.
  3. Select Always Activate from the drop-down on the right edge of the screen.

Use a Different Browser to View Your Articulate Content

If you can't update your Flash Player plugin right now and you don't want to risk using the vulnerable plugin, you can view your Articulate content in a different browser until your Firefox plugin has been updated to the latest version.
