BoxCheck is an extension which uses shift click to check or uncheck a range of boxes.

I hope someone else out there finds this as useful as I do. If not, at least I still like it.
To use the extension, simply install it. Then, once you're restarted FireFox, you can mark a group of checkboxes by marking the first one and then marking the last one while holding the SHIFT key similar to how you can select multiple, contiguous files in Windows Explorer. You can also un-mark boxes by unmarking the first and unmarking the last while holding SHIFT, too.
