Clear Firefox cache in Selenium IDE

firefox, selenium

Solution

In Python this should disable Firefox cache:

profile = webdriver.FirefoxProfile()
profile.set_preference("browser.cache.disk.enable", False)
profile.set_preference("browser.cache.memory.enable", False)
profile.set_preference("browser.cache.offline.enable", False)
profile.set_preference("network.http.use-cache", False)
driver = webdriver.Firefox(profile)

hope this helps someone.

Problem

I'm using Selenium IDE to test a web application. Sometimes my tests succeed even though they should have failed. The reason is that the browser happens to load a previous version of a page from the cache instead of loading the newer version of that page. In other words, I might introduce a bug to my app without being aware of it because the tests may pass after loading a previous working version instead of loading the new buggy version. The best solution I could have thought of is to delete the browser cache before running the tests. I have a Selenium script in which I run set-up selenium commands before running the tests. Is there a selenium command to clear Firefox cache? Alternatively, is there another way to prevent loading pages from the cache during the tests?
