It looks like I’ll be switching back to Firefox as a Web browser, over Christmas, as Google Chrome is set to block install of all extensions that don’t come from its own extension store. There is no way I could tolerate Google Search without GoogleMonkeyR, or Facebook without F.B. Purity. Also not on the Chrome extensions store are: After The Deadline; Flickr: Show All Sizes; and RSS Subscriptions with FEED: Handler Support (the only RSS address bar buttonizer that seems to work with FeedDemon).
