How-To: Speed Up, Customize, and Secure Firefox, Chrome, IE8, and Opera
Optimize Opera 9
1. Disable Server Name Completion
Opera 9 does a great job of trying to figure out what website you are trying to get to based on your browsing history. To speed up the browser and have it take less of a toll on your system, it is a good idea to disable this feature.
Click on Tools, select Preferences, and click on the Advanced tab.
Click on Network in the left hand pane of the window and select Server Name Completion. Uncheck Look for Local Network Machine and Try name completion, using and click Ok.
2. Increase Cache Image Time and Other Cache Related Tweaks
By increasing the amount of time cached images are using, the web browser does not have to reload the images every time you go to the website. In the end, this will speed up web browsing.
Click on Tools, select Preferences and click on History on the left side of the window. Where it says Disk Cache, change the number to 100MB. This will increase the speed of the browser by letting Opera store 100MB worth of information on your hard drive so it doesn’t have to start the rendering process again.
We also want to make Opera check for new images less. By default, Opera checks for new images every 5 hours. As you know images can take up an enormous amount of bandwidth, so limiting the reload frequency of images is ideal. We recommend you change the value to 24 hours so it will check daily for new images.
If you don’t see the image you are supposed to on a website, press F5 while on the website to manually refresh the cache and load the correct image.
3. Increase Total Number of Connections
As with the previous browsers covered, Opera also has the ability to increase the total number of connections to a website. Having more connections to the website should make the page load faster.
In the Opera address bar type: about:config

In the quick find text box, type connection. Change Max Connections Total to 32. This will tell Opera to make 32 connections to the website. Do not change any of the other preferences on this page, just click Save. If you change the Max Connections of the Server, you may increase the loading time instead of decreasing.

4. Redraw Web Pages Instantly
Opera by default redraws the website every second. While this may seem fast, when browsing multiple websites it can get annoying. Thankfully, there is an option in Opera to change the redraw time instantly. Instantly means as soon as Opera is done rendering the page behind the scenes it will display it.
Click on Tools, select Preferences and click on Browsing. Under Loading, change it to Redraw instantly and click Ok.
5. Change Browser Title
If you haven’t noticed, every web browser includes its name at the top of the screen. While this may not affect the performance of the browser, it would be awesome to change the name of the browser to something you like.
To do this, open a new Opera browser window and paste into the address bar: opera:config#UserPrefs|Title
This will take you to the browser’s configuration screen and you should see a text box with the word Title next to it. In that text box, type whatever you want to display at the top of the browser and then scroll down to the bottom and click on Save. Restart the browser and the name will now be whatever you typed in.

6. Change Skins
Like most other browsers, Opera has the ability to support different skins. No one should be forced to use the default skin of a web browser if there are better options available.
Opera’s official skins can be downloaded from here. It doesn’t matter which skin you choose since they are all installed the same way. We are going to choose the Crystal Oynx Bull skin found here.
To install the skin, click on the Download Skin button. Opera will apply the skin and ask if you want to keep it. If you like the way the skin looks, click Yes, otherwise click No and keep searching.
