Google Chrome is now testing a new option that synchronizes extensions and their settings. The feature is available in the most recent Dev Channel build, but you need to add two flags that enable this feature: --enable-sync-extensions --sync-url=https://clients4.google.com/chrome-sync/dev. For e.g., in Windows you need to edit a Chrome shortcut: right-click on the shortcut, click on "Properties" and append a space followed by the flags above to the target field.
Chrome is the only popular browser that doesn't have native support for feeds: doesn't detect, preview, or let you subscribe to feeds using your favorite feed reader. These features are implemented in Chrome's RSS subscription extension, which was supposed to be bundled with the browser, but didn't because not many people subscribe to feeds and orange icon would've been distracting. A Google Chrome engineer offered a detailed explanation.
