How do I work out which browser I'm using?
If you know what browser you are using, then skip to the relevant instructions below. If you do not know the type of browser you are using, click on Help on the toolbar at the top of the browser screen. A drop down menu will appear, the last entry will say About Internet Explorer, About Mozilla Firefox, or something similar. The entry refers to which browser type you are using - you should then refer to the relevant instructions below.
Click on the Tools menu and select Internet Options. In the General page under Browser History, select the Delete... button. Either select and delete each section: Temporary internet files; Cookies, History; Forms data and Passwords; or select the Delete all... button at the bottom to clear everything.
Mozilla Firefox 8
Click on Tools and Options. Firefox bundles cookies, forms and history under the heading ‘history’. Click the privacy tab, then on “clear your recent history”. Select the period you want to delete. Click on Details to select cookies, forms etc.
To delete passwords click on the security tab where you can view all the passwords saved when you browse the web. You can delete them here and remember not to allow Firefox to save them in the future.
In Firefox you (or someone accessing your computer) can actually read the passwords saved on your system. If you use the same passwords for many things consider changing them all if you have allowed your browser to save any.
You can also adjust how you want Firefox to store your data under the privacy tab.
To remove history go to History, and click Clear History.
To remove cookies go to Settings (right hand side), Preferences, Privacy tab and click Remove all Website Data (or Details to select certain sites).
Chrome, Opera and other browsers
There are many new browsers on the market, so it is always advisable to search for advice on your own browser. For example this tutorial shows you various security measures on Opera, or you can see the settings for Google Chrome.
