Chrome: If you frequently use the About: pages in Chrome and want a speedier way to access them than typing in the URL in the address bar, ChromeAccess adds a quick-access button in the navigation bar.
You can always type about:cache or about:memory to access the hidden features in Chrome, but for frequent access the two-click interface of ChromeAccess is much faster. Click on the navigation bar icon of ChromeAccess, a small Chrome logo, to access popular pages including the extensions menu, download history, bookmarks, and even more obscure items like cache info and histograms.
ChromeAccess is free and works wherever Chrome does. Have a favourite Chrome extension or trick to share? Let's hear about it in the comments.
