You can use the "Clear Private Data" button in the Firefox preferences to remove all of your history, cookies, cache, and passwords. If you want to remove ''just'' the history, you can use one of these add-ons: https://addons.mozilla.org/mobile/addon/cleary/ https://addons.mozilla.org/mobile/addon/clear-mobile-history/ Note: Because of a bug in the current version of Firefox, it might take a few minutes for old history to be cleared from the "all pages" list. This will be fixed in a future version of Firefox.
