Rated 2 out of 5 stars

I used to LOVE this plugin.

But I've just installed it after a year and it doesn't work on my Firefox 2.0.0.12 (Vista OS). I keep receiveing the following error:

"The upgrade action for version 0.9.3 failed because: units has no properties."

Is this a known problem and is a fix on the way??

This review is for a previous version of the add-on (0.9.5.2).
