One of my all time favorite plugins for Firefox.

Anytime I want to open mutiple links from a single page such as is found on pages like eBay, YouTube, and especially in browser based emails pages like Gmail...

This app simplifies the task greatly.
I recommend you try it. It should be a default in all browsers.

been using this for over a year, great

It works very well, but sometimes activates itself without me doing anything. And opens huge amount of links I didn't wanted.

you could let us choose between opening automatically or after scroll click/popup icon left click after lassoing. Great extension.
Ps.: It opens the context menu each first lassoing.

Useful but buggy
