How to Fix a Slow Browser
A Web browser is a program that allows you to surf the Internet. Web browsers let you enter any URL and direct you to the corresponding website or web page. For several reasons web browsers may become slow. Even if your Internet connection is fast, your browser may become slow when it builds up cache files and Internet history. You can also increase speed by increasing the amount of disk space used by your browser to surf the net. This process will help you troubleshoot both Internet Explorer as well as Mozilla Firefox.

Click on "Tools" and select "Internet Options." Click on the "General" tab.
Hit "Delete" under "Browsing History." Place a check mark next to "Temporary Internet files" and "Cookies." Click on the "Delete" button.
Hit "Settings" under "Browsing History." Drag the slider to the right to increase the amount of disk space used by your computer to browse the Web.
Launch Mozilla Firefox from the Start menu.
Click on "Tools" and select "Clear Private Data."
Place a check mark next to "Cache" and click "Clear Private Data Now ." Hit "OK."
