Twitter has made changes so that this won’t happen in future, but if you are among this small group of users who access Twitter from a public computer then you should clean Firefox cache before leaving that public computer. There are many ways to do this.

Easiest way is to clean the Firefox Cache using the “Forget about some browsing history” button in the Firefox browser. This button is located on the Firefox toolbar, but if it is missing then you can add it from the Firefox customization feature (click on Firefox menu and then select “Customize”). Using this feature you can completely remove all the browser history for past 5 minutes, 2 hours or 24 hours.
