If you have been using Firefox web browser in your Android device than you must have noticed how much internal memory space it consumes to save the browser history and other types of cache. On my Android smartphone, the space consumed by Firefox quickly rises to as much as 200 MB only in a couple of days. On a smartphone with only 1.6 GB internal memory, this is very undesirable as this leaves very little space for other apps to be installed. One solution is to regularly clean the cache used by Firefox app from the Android settings section, but that also wipes out the settings saved by Firefox. A much better solution is provided by the CleanQuit add-on for Firefox in Android. This add-on adds an extra menu item that allows you to clean all the browser cache before quitting the Firefox browser.
After the installation of the CleanQuit Firefox browser, you can press the menu button on your Android device to bring up the Firefox menu. At the very bottom of this menu, you would find the new CleanQuit option. Tapping on CleanQuit will first clean all your browser history, cookies, and cache and then quit your Firefox browser.
In the options for the CleanQuit extension (that you can access by typing about:addons in the address bar), you can control which items in your Firefox browser are cleaned by this add-on. You can check or un-check any of these items to enable cleaning these items. Typically the CleanQuit extension can clean the cache, cookies, site preferences, offline apps, browsing history, form data, download history, saved passwords, sessions and recent tabs.
Conclusion: The CleanQuit add-on for Firefox can help you keep your Firefox browser clean and fast in your Android smartphone. It can clean all the possible kinds of the data accumulated during your web browsing sessions at a single tap.
