If you double click an html/web document (files with the extension of .htm, .html, etc.) your default browser will open. Once it opens, you can check the version in the help or about menu.

You can have as many internet browsers you want in your computer but you can only have one default browser meaning, the browse which opens when a web document is double clicked.

Google chrome is fast but is lacking in features compared to firefox and the new internet explorer.

There are dozens of companies providing access to the internet, and many of the programs work quite well. Sometimes you may find yourself having trouble staying on the internet. Imagine working on a project for work and school, and having your browser shut down every few minutes. This is extremely frustrating and it makes it hard to do simple work. If you find your internet browser shutting down frequently, you need to diagnose the problem and find a solution.

1

Download a different internet browser such as Opera or Firefox. Both products are free of charge and might fix your problem.

• 
  Step 2
  Install the browser of your choosing and try to surf the web. If the problem is with you provider’s browser then the problem should be solved. However, if your browser continues to shut down you may have a spyware or adware problem.
• 
  Step 3
  Run a scan of your computer for adware and viruses by using your virus protection program. Since they only find a small portion of the viruses, especially if your service is out of date, you’ll need to download Spybot Search and Destroy.
• 
  Step 4
  Let the Spybot program run through your computer to find any problems.
• 
  Step 5
  Add the Ad-Aware program to your computer and run the program. Combining these two programs will allow you to search for any adware or viruses on your computer that could be causing your browser to shut down.

  Tips & Warnings
  • 
    Call your internet provider and ask if anyone else is experiencing problems. In some cases the system may be experiencing troubles, in which case these solutions will not work.
  • 
    Update your virus protection program frequently and scan for viruses and spyware at least once a week. This will help you stop the programs before they have the chance to stop you

While jezzbb is largely right, there's a program called BrowserChooser that will let you chose which browser is used anytime you click on a link.

Any modern browser will let you save sites as "favorites" or "bookmarks." Most will also import your bookmarks/favorites from other browsers. There are third-party products that will let you synchronize those between several browsers, too.

Firefox, especially with the NoScript and AdBlock extensions installed, is generally much safer than IE. Chrome has gotten to be fairly good, too, and Opera is very reliable. It's a good idea to pick a browser you like for everyday surfing and just use IE for running Windows Update (which requires it).
