Walter Mossberg recommends Safari (mac) and NetCaptor (Windows), as Microsoft’s Internet Explorer has stagnated in recent times. One of the reasons: Tabbed Browsing.
With tabbed browsing, you can keep multiple Web pages open at the same time, on the same screen. Only one page is visible at a time, but the others are identified by a row of tabs, usually at the top of the screen. To switch screens, you just click on one of the tabs. The new page appears instantly, because it has already been downloaded.
Tabbed browsing is the biggest fundamental improvement in the Web browser in years. It’s like quickly navigating among paper folders in a packed file drawer by reading the staggered tabs that protrude from their top edges.
With tabbed browsing, you can open all your most-visited bookmarks or favorites with one click. They could remain open all day, updating in the background. You can view them at any time, and in any order, by just clicking. You can also open any new Web page or link in a fresh tab of its own. Or, if you have groups of related favorites or bookmarks arranged in folders — say, a folder labeled “Red Sox” that contains a dozen favorite sites about the fabled team — you can open them all with a click.
Tabbed browsing is especially great with slow dial-up connections, where waiting for a new page to load can be irritating. But I even love using it with broadband connections.
Mozilla and its variants like Galeon (which is what I use) also allow tabbed browsing.
