On 25, I can't exactly reproduce error.png, but the line segments do slightly change as I zoom in.  I don't know enough about SVG to even know whether that's a problem.

You're talking about using the page's own pure-mousewheel-based zooming, right? (not Firefox full-page-zoom)

I get the same results in Firefox as Chrome there (and the changes are subtle, and presumably triggered by scripting in the page rebuilding the path or something). I'm using Linux, and I tested Firefox 25 and Nightly.

Reporter: can you provide your OS version & Firefox version (from top of about:support)?
