Fun New Way to Improve My Spanish Vocabulary

So I haven’t been trying very hard to acquire the language lately, but I have been reading from Spanish books on my Kindle and browsing Spanish Amazon, Wikipedia, etc. I haven’t learned very many new words this way, but I have found that I am able to recall words that I already know more quickly and easily. What I really need to do is just sit down and study some new vocabulary, but until then, I have found a Chrome application that will throw foreign words (in the language of your choice) into the web pages that you visit. There are five different levels of immersion. This app has a lot of bad reviews because sometimes the substituted words are out of context or get translated as a homophone. For instance, I was reading someone’s blog just now about going on a trip and she suggested to pack light. The translator used the Spanish word “luz” for light, which would be nothing more than a reminder to take a flashlight with you, lol. However, I am having fun with it, and hopefully I will pick up a few words along the way. At least, using this extension all the time, I won’t be able to forget about my language-learning goals in the daily swing of things.
