How-To: Speed Up, Customize, and Secure Firefox, Chrome, IE8, and Opera
2. Turn Off SmartScreen Filter
If you have used Internet Explorer 7, you are no doubt familiar with the Phishing Filter. This filter was a very useful part of Internet Explorer 7, but slowed web browsing to a crawl since it constantly analyzed the websites.
Microsoft has redesigned the Phishing Filter to make it less intrusive and renamed it to SmartScreen Filter. Unfortunately, the SmartScreen Filter is still intrusive and still slows down web browsing.
Shutting off this filter will help speed up web browsing and since we are going to install another add-on later that will perform this task, it makes the SmartScreen Filter useless.

To turn off the filter, click on the Safety button and highlight the SmartScreen filter. Click on Turn off SmartScreen Filter and you get a pop-up that wants you to verify if you want to turn off the filter. Verify that the filter is actually going to be turned off and click Ok.
3. Turn off Feed Reading Features
RSS readers have revolutionized the news industry with their ease of use. Many browsers now have the capability to keep track of RSS feeds. Unfortunately, checking the feeds will slow down web browsing. If you really want a feed reader, you should use a dedicated application, such as FeedDemon or any of the other standalone programs.
Click on Tools, select Internet Options and click on the Content tab.
Click on the Settings button under Feed and Web Settings.
On the Feed settings window, uncheck the box next to Automatically check feeds and Web Slices for updates. Under the advanced section, uncheck Turn on feed reading view and Turn on in page Web Slice discovery. Click the Ok button on the Feed settings window and on the Internet Options window.
4. Disable Java Plug-in 2 SSV Helper
The Java Plug-in 2 SSV Helper is an unnecessary add-on for Internet Explorer. The name makes it sound like it is required for Java to run properly when using web applets. However, the newer versions of Java don’t require this add-on to be enabled. The more add-ons that are present on a system, the more likely the system is to slow down so it is a good idea to disable this add-on.
To turn off this add-on, click on Tools and select Manage Add-ons. Click on Java Plug-In 2 SSV Helper and click on the Disable button in the right hand corner of the window. Click on Close and restart Internet Explorer. The add-on is now disabled.
5. Reregister actxprxy.dll
actxprxy.dll is a very important dynamic link library file crucial to the stable running of your computer. This process belongs to the ActiveX program for Windows. It controls the way the various ActiveX controls run and communicate on your system. This tweak will re-register the dll file on your system and potentially speed up web browsing.
This tweak may not speed up Internet Explorer 8, but may help fix IE8 if it is sluggish, and how you perform this tweak depends on what version of Windows you are running.
If you are running Windows XP, press the Windows key and R. Then paste the following in the run box: regsvr32 actxprxy.dll
If you are running Windows Vista or higher, click on Start and type “cmd” in the search box. Right click on the cmd result that displays and click Run as administrator. Paste the following text in the run box: regsvr32 actxprxy.dll.
If it was successful, you will see a message stating that the DLLRegisterServer in actxprxy.dll succeeded. This means the re-registration of the file succeeded and the tweak ran as planned, click Ok to close the window and then close the command prompt window.
6. Install WOT
Web of Trust (WOT) is a very useful Internet Explorer 8 add-on that warns you of risky and potentially dangerous websites. It uses a red, yellow, green and grey color scheme. Red means the website is bad, yellow means the website is potentially bad, green means the website is good and grey means the website has not yet been rated or does not have enough ratings to mark it as a good or bad website.
WOT is dependent on how the other users of the program rate particular websites. Since it takes more than one user to rate a website as good or bad, it makes this add-on safe.

Click here and download the WOT add-on. When the download window displays, click on the Run button so the program automatically starts installing after it is downloaded.
When WOT is ready to install it will display the EULA and make you accept the agreement. Please read the agreement, put a checkmark in the appropriate checkbox, and click on Install.
After the program is installed, WOT will open to the configuration page and ask you what protection setting you want to use. We recommend that you choose Maximum Safety since it will protect you from the extremely dangerous sites. However, this may slightly slow down your web browsing speed by less than a second, but this is a small price to pay for the added protection. If you don’t want this delay, select the Light protection setting and click Finish.

When you visit websites you will see a red, yellow, green or grey circle at the top left hand corner of the browser window.
