Rated 4 out of 5 stars

it's awesome add-on!
but I can't find auto url
is there any auto url?

This review is for a previous version of the add-on (0.2.7.1-signed). 

Do you mean auto-switch rules?
You can create rules in "Fire IE Switch Rules Preferences" dialog. (Right click URL bar icon -> Switch Rules)
