I’ve written a new version of my LibraryLookup script for the San Francisco Public Library that works with Google’s Chrome browser. If you’re running Chrome, you can try it out by clicking this link. It should work regardless of your OS platform — in fact, it even works on Chromebooks! Note that this version of the script is a substantial rewrite from the Firefox version, so I’ll be especially interested to hear any bug reports. It works pretty well for me so far, but I still don’t use Chrome as my main browser.
Also, note that because LibraryLookup uses cross-site scripting, it has to run as a Background Page in Chrome, because of the way the browser was designed. That means it’s consuming some small amount of memory all the time, even when you’re not browsing Amazon. The amount of resources used should be negligible, but you should be aware of this before you install it. Enjoy!
