My main objective is to clear the cache permanently for the application which i am accessing using Firefox. The customer with whom i am working with requires a permanent solution to clear cahce without the effort of the user to access the settings and clear cache from there.I have found a solution to clear cache by setting FF as private browser. On doing so it is almost clearing the entire cache but there is still some residual cache left. The residual cache that is remaining is called "addons.mozilla.org". This is creating a lot of issues for me. Many user are complaining that there is still cache left and this is the one ("addons.mozilla.org"). The users dont want to go to settings and clear the cache by themselves, they are too busy to do so. Please provide me a permannent solution to clear the cache once and for all without the need to access the settings to clear cache. PLEASE HELP
