Safari 4 BETA
Top Sites
Thanks to Top Sites, you can enjoy a stunning, at-a-glance preview of your favorite websites without lifting a finger. Safari 4 Beta tracks the sites you browse and ranks your favorites, presenting up to 24 thumbnails on a single page. You can even customize the display by pinning a favorite site to a specific location in the grid. That locks it into position, so you know just where to find it every time you open Top Sites.
Wonder which sites have changed since your last visit? Sites with a star in the upper-right corner have new content. A single click opens the page and updates its thumbnail. Whenever you want to return to your ever-evolving Top Sites page, just click the new Top Sites button in the bookmarks bar.
Google Chrome
When you open a new tab, Google Chrome preloads it with useful information. With one click, you can get to the web resources you use most often. To open a New Tab page, click the + icon next to the last tab.
Features such as:
- Links to websites you visit the most
Chances are you visit some websites on a regular basis. The New Tab page provides image thumbnails and links for those websites automatically.
Right-click a website to access options to open it in another new tab, in a new window, or in incognito mode. Click the Show full history link at the bottom of the page to see your entire browsing history in Google Chrome.

Tabs on Top
Tabs offer a great way to have multiple pages open at the same time in a single browser window. And to switch back and forth with a click. Now Safari takes tabbed browsing to new heights — to the very top of the browser window — instantly providing more room for you to enjoy the sites you’re reading.
Safari also makes it easy to create and manage tabs. To create a new tab, just click the + button in the upper-right corner of the Safari window. Want to rearrange tabs? Simply drag a tab by its handle and drop it in a new location in the tab bar. You can also use the handle to drop a tab into another Safari window. Or quickly create a new window by dragging the tab out to the desktop. You can create a bookmark from a group of tabs. Or even tell Safari to open a set of tabs every time you open a new Safari window.
Google Chrome
Google was first (as far as I know) to offer the tabs on top, just google for “Google chrome screenshots” and you’ll see how they look.

Smart Address Field
Just start typing, and the Smart Address Field instantly offers suggestions. You’ll see the Top Hit and the best matches from your browsing history and bookmark collections, each in their own easy-to-read section.

Explore Google Chrome Features: Address bar
In Google Chrome, you can get anywhere on the Web with one box. The address bar that sits at the top of the normal Google Chrome window simplifies your Internet experience by doubling as a search box. You can also use it to bookmark websites and stay aware about the security of a website.

I can’t really use either one since neither offers good password remembering plugin/functionality, that’s why I use Opera.
Have a look at Smarter TakeOut – online take out software

I think both stole the “Top Sites” idea from Opera’s “Speed Dial,” no?
Or maybe the Speed Dial addon for Firefox was stolen from Opera, then Safari and/or Chrome stole it from Firefox… ; )
Tabbed browsing, mouse gestures, speed dial – weren’t they all stolen from Opera?
That’s well spotted Lee!
Thanks for the comment.
I wish Opera had a way to protect these kind of features.
