Firefox only: The next time you're doing a little online shopping, consider downloading the Firefox add-on Caveat Emptor first. It quickly lets you know if the product you're looking at has been recalled or is on a safety watch list.
Caveat Emptor — Latin for "let the buyer beware" — reads the meta data on the product web page you're viewing and checks it against a list of products that have been recalled by the Consumer Product Safety Commission (CPSC).
Once installed, you can access it by right-clicking your mouse button. You'll get the option to check the CPSC monitored products or access a list of RSS feeds for all kinds of recalled products from toys to sporting gear.
Right now, the Caveat Emptor add-on is a pretty barebones affair. According to its developer, though, future plans include improved search and a more user-friendly API.
