You may need to install MR Tech Toolkit Firefox extension first. I Also use All-in-one Sidebar too (excellent little addition).

All you needed to do is click on the install on maps.ovi.com and select to ignore compatablilty.

After re-start right click on the extension in the extension manager and select "force compatability" or something like that. Re-start Firefox and hey presto it works.

That easy. None of this script modification malarky.
