Have you ever had the feeling that someone was looking over your shoulder to see what sites you were visiting at the moment? The currently active site might be a harmless one but the text of the tabs that are open as well might reveal something that you would love to keep secret.
One way to handle this situation would be to rename the tabs using the Firefox extension Rename Tabs. This extension lets you rename any open tab with several default phrases such as Mozilla, Google or Problem loading page. It is also possible to create a custom text for a tab, maybe something sweet like I love you would be a nice idea as well. That is, if you want someone to see it, hehe.
There is however a small problem with the Rename Tabs extension. I was not able to find out if it is possible to save renamed tabs so that the tab of the site would appear renamed whenever you would load the website.
Update: The Rename Tabs extension is no longer available, it appears that the author has removed the add-on from the official Mozilla Addons repository. There does not seem to be a comparable add-on available at the moment either.
What you could do to increase your privacy, is to reduce the tab width of the browser tabs, so that the page titles are not displayed in full there. You can do that quite easily by opening lots of blank tabs until all tabs are reduced in size, or change the maximum and minimum tab width values in the Firefox configuration.
