SVG plugin required - SVG will not display

[Jacobus]

Binary package hint: firefox-3.0

Most SVG websites used to work in Firefox until I updated yesterday (27 May). Now some are not rendering the SVG and says that I must install a plugin:
Example

I would rate this a high priority as existing sites are loosing their accessibility, which is bad for the sites and bad for Firefox.

Kind regards,
Jacobus
