How to turn off the Firefox cache?
Turn off the caching for a particular page. the correct way is to set the cache directive in Http request:
turn the entire Firefox caching capability off through its about:config page
network.http.use-cache = false.
If you use FireBug, on the Network tab's drop down menu there is an option do disable the browser's cache.
You can force all requests relating to a refresh to actually be requested from the server (bypassing any already cached content, and updating the cache with the new version) by using Ctrl+F5 instead of just F5.
This does not work for requests made by the page within client-side code though. When that is a problem you need to use the
POST method (
POST requests should never be cached) instead of
GET or add an ever-changing value to the query string (such as the current time in ms).
