Two more One new and one old lifehack to make your e-world better.

• Mozilla Ubiquity. I’ve been evangelizing on behalf of this do-everything command-line Firefox plugin for a while, but you should really try it. Even non-technical people think it’s awesome. You can search Wikipedia, Google, Yahoo, eBay, Ask, Flickr, IMDb or Amazon, add TinyURLs, map addresses, twitter, digg, email, check weather, translate…and that’s not even all of it. You should get this. Seriously.
• Mail Goggles. The Newest Google Labs rollout will help “prevent you from sending messages you might later regret.” How? By making you do a few simple math problems that might take you too long if you’re tired, drunk or otherwise incapable of rational thought. (HT: Jeff)
