Wonderful Firefox Add-On Rated 5 out of 5 stars
I made the Add-On called 'SnapLinks (EladKarako Mod)', which also uses right mouse button to open up a mass of links in tabs.
Multi Links works far more better & efficient then snapLinks (although both uses roughly same idea). But the only one compatible with Firefox 3.6(b3/+..) new script-engine (runs scripts async and in background).
long story short.. snapLinks users, switch to Multi-Links.
