Is it better than Web Developer Toolbar > Miscellaneous > Display Line Guides ?

I just installed but both option are showing disabled in Right Click > FoxGuide

I'm on Windows 7 and using Firefox 3.6.12 and I also have "Web Developer Toolbar" installed.

Don't know how to use FoxGuide?

This review is for a previous version of the add-on (1.1). 

You can switch on the addon by clicking a purple icon at the right corner.
