Here is the list of annoyances that it takes care of:
- When the right-click context menu is completely disabled, or partially disabled on a site
- Pages that interfere with you copying, pasting or cutting data. This can be sites that block you from pasting information into forms for instance
- Web pages that prevent the resizing or moving of the browser window
- Websites that mess with the link target attribute, for instance by opening all left-click links in a new browser window
- Pages that prevent copying, send back links that you click on to tracking servers, or pop up definition links when you hover over contents
The Chrome extension can break certain pages. Some users have for instance mentioned that it conflicts with Gmail, Google Docs and Google Calendar. The developer for this reason has integrated a whitelist into the extension that blocks the extensions' functionality on those pages.
The reviews at the Chrome Web Store hint at some of the websites and services that are not working properly. While you won't find all of your favorite services listed here, it may be a good starting point. (via)Advertisement
