LJ has recently implemented an irritating new technology - the Snap link preview. Though this is disabled by default for your own journal, you might still end up seeing it in communities. If it annoys you as much as it does me, and you're using firefox, you can adblock it out. Just add *snap.com* in your adblock text window. Poof! No more annoying pop-ups if you happen to mouse over a link. No more drag on your click-through time. Hurray!
