browser extension for Google chrome

2012-10-01 update: because of questionable design choices from the developers of Google chrome, the pgn4web project has discontinued the chess games viewer extension. As a result the information below is obsolete and is kept only for historical reasons; more info at the wiki page.

Based on pgn4web, the chess games viewer extension for the Google chrome web browser provides an interactive chessboard showing chess games from links to *.PGN URLs and from PGN text, using context menus and page actions. Live chess broadcasts are supported.
Once you have installed the extension, an icon should appear in the address bar of this page, having recognized this link to chess games in PGN format; hovering the mouse over the link, the mouse pointer icon should highlight the link as chess games; manually right-clicking that link the chess games viewer context menu item should be available; finally, you can select the following PGN text and load the game in the chess viewer using the right-click context menu:
