The web browser is probably the most essential application on your PC; there is no better practical way of staying connected to news, your friends, and most importantly, the lulz. But whether you’re using Internet Explorer or newly minted Chrome, each of today's popular web browsers has different strengths and weaknesses. Mozilla Firefox is feature-heavy and relatively fast, but can get terribly unwieldy when crammed with juicy add-ons. The newest version of the once dominant Internet Explorer is a quantum leap above previous buggy versions, but remains slow. And while both Opera and Google Chrome are blazingly fast, they currently lack customization.
No matter which browser you use, you want it to fit your personal needs and tastes. With this guide, we will show you the essential initial tweaks everyone should make to “awesomize” their browser. Whether it’s accelerating browser page-load performance, boosting security, or just improving the look of the interface, we teach you the tweaks that we think should be implemented the first time you start up a browser after installation.
We cover comprehensive step-by-step instructions for Internet Explorer 8, Mozilla Firefox 3, Opera 9, and Google Chrome, starting off with general web optimization tips. So jump into the guide and start tweaking your web browser!
General Optimization Tips
Use OpenDNS
OpenDNS is a replacement DNS server for your computer or router. Generally, this DNS server is faster and more stable than the one provided by your ISP. Since it allows for faster web browsing, this is a good tweak to perform on your computer.
Depending on the operating system you are using, OpenDNS may have a different setup. For the purpose of this guide, we are going to assume that you are using Windows Vista. However, you can find the other setup guides located here.
Click on the Start button, select Control Panel and click on View Network Status and Tasks.
Click on the View Status button next to your Local Area Network and click Properties. Select Internet Protocol Version 4 (TCP/IPv4) and click on Properties. Click on Use the following DNS server addresses and type in the following:
Preferred DNS Server: 208.67.222.222
Alternate DNS Server: 208.67.220.220

Click Ok and close the connection properties window. To see if you are using OpenDNS correctly, click here. If you see a welcome message, then you are using OpenDNS and no further configuration is necessary.
For more information on how to tweak your DNS settings, refer to our full DNS guide here.
CCleaner
CCleaner is a simple, lightweight program that deletes temporary files, history, and other unused files from your computer. In addition to the file cleaners, it also has a registry cleaner.
Download CCleaner from here. Download the latest version. CCleaner will try to add a Yahoo! Toolbar and make several other changes to your system. If you don’t want it to do this, uncheck the options in the wizard. We recommend that you create a desktop shortcut for ease of access, though.
When you open CCleaner, the main window will display several options. We are going to clean the temporary files from all the browsers and Windows, so we don’t need any of the other options.
Click on the Analyze button to start scanning for temporary files. You will need to close your browser to delete them, so do so now. After the program is done analyzing, click on Run Cleaner to delete the files. CCleaner will alert you it is going to delete the files, click OK to proceed and delete the files from your computer.

Optimize Internet Explorer 8
Internet Explorer 8 is the newest version of Microsoft's built-in browser and similar to previous iterations of IE it still has speed issues. Microsoft has improved the browser, but it still slightly lags behind Mozilla Firefox in terms of speed. Here's how to improve it.
1. Increase Internet Explorer 8's Connection Limit
By default, Internet Explorer 8 establishes six simultaneous connections to a web page. Each of these connections downloads a certain part of the website, whether it be the main page itself or some of the pictures. Six connections may be enough for smaller websites that don’t use much Flash, but for more complex pages like the ones on Facebook, Internet Explorer will be slow at rendering the page.
You can increase the connection limit by merging a registry file into your computer’s registry.
Download the registry file from here and save it to your Desktop. Double-click on the file and click on Yes to merge it to the registry.
After the merge, you will receive a message stating the merge was successful, if you don’t, try merging the file again.
