Trying to access a HP ESL G3 tape library using Firefox, I get the message that additional plugins are needed. How do I found out what plugins are needed?

If HP doesn't have a ready answer for this, you can look at the HTML source code of the page. You aren't going to read every word, but instead run a couple of Find operations.

  • Select the entire page using Ctrl+u
  • Right-click and choose View Selection Source
  • After the page loads, open the find bar using Ctrl+f
  • Search for the following:
<object

The tag usually contains a "type" such as "application/x-shockwave-flash" that Firefox will try to match with one of your plugins. There might be multiple <object> tags in the page, so try Next until you've seen them all, and make a note of the various types you find.

  • Search for the following:
<embed

Similar process here.

  • You're done with source view. You can close the window.

Can you report back on what types you found?
