Provides two options for comparing different versions of your Dropbox files: 1) an external diff tool, or 2) a side-by-side diff within your browser. This can be TortoiseMerge, KDiff3, FileMerge, or any tool which can be triggered from the command line.
From www.dropbox.com, in the "Version history" of any file, a column is added which allows you to select two versions to compare. Click the "Diff" button to trigger your configured diff tool, or the "Inline" button to view the difference in-browser.
Supports Windows, Mac, and Linux as far as I know, though I can't be sure every possible configuration is covered.
Please let me know if you run into any issues at http://blog.vicshih.com/2011/09/dropboxdiff-chrome-extension.html .

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
