Works fine over here...

Yep.  "font-size:20" is not valid text/css, so we report the error.  The page should be fixed.

Just tried it again using a new installation of Deerpark 1.0+ 20050712
and it works! 
However some unexpected differences:
1. loads But now 10 errors are reported on JavaScript console immediately.
3. ten errors reported when right click.
5. Using back arrow displays whole page (ie including large SVG image) and no
   additional errors are reported on javascript console.

Hi Bill, this is invalid I'm afraid. Please don't assume that just because a document doesn't render in Moz that it's because of a bug in our implementation. Errors in the JavaScript console usually show there is an error in the SVG, not in moz. The SVG out on the web is incredibly buggy. Hence the need for the document at

  http://jwatt.org/svg/authoring/

In the case of the document you link to, the author needs to fix their SVG according to the following sections of the authoring guidelines I just linked to.

  http://jwatt.org/svg/authoring/#avoid-css
  http://jwatt.org/svg/authoring/#css-and-units

The reason you don't get the errors the second time may be because of the new fastback feature. (When you press the back buttons documents are loaded from an in memory cache, not on disk cache, so they aren't reparsed.)

Why don't you update to Firefox 1.5 release candidate 2? Things have moved on a fair bit from your current version. As well as trying only to file bugs on things you know aren't errors in the SVG, please make sure you file bugs only on recent builds.

With that installed, updating to the final version (when it's released) will simply be a case of clicking Help > Check for Updates...

-> invalid
