I think it's a great tool. I'm using Firefox v3.0.4 and it works great! Just push your left mouse button when your mouse cursor is over the first check box you want to check and draw your the line over other checkboxes you want to check while you still pushing your left mouse button and you got it! Big thanks to author!
Doesnt seem to be compatible with my Firefox 3.0.4 for some reason
It seems not to be compatible with firefox3.1beta2 or above.
This is a nice addon, it speads up the selection of checkboxes. Mainly useful to delete messages from your web email.
It is a bit buggy (the checkboxes becomes unselected in some cases) but it is worth to install. Keep up the good work.
very very good for checkbox.
