Problem with Customization Rated 3 out of 5 stars

Firefox 12, no assistant, no way to customize. Can someone please just let me know if I'm missing something, or does this not work with Firefox 12? I would like to use this extension; it was just what I was looking for. I cannot figure out how to choose the modes (tried both 1.5.7 and 2.0 in Firefox 12).

This review is for a previous version of the add-on (1.5.7). 

I'm sorry but I can't reproduce your issue. If you could file a bug report at http://sourceforge.net/p/autosizer/tickets/ we could try to figure it out.

Thanks
