How to Clear the Firefox Browser Cache With Selenium WebDriver/geckodriver shows how to clear the Firefox site data, including the cache and cookies, with Selenium. There are two version of the script described in detail in this article.
- clear_firefox_61_cache.py - Written for Firefox 61 released on June 26, 2018. The script will keep working until Firefox's slow-changing preferences page is modified by Mozilla.
- clear_firefox_57_cache.py - Written for Firefox 57 released on November 14, 2017. The script should work on version of Firefox with a similar preferences page.
The scripts both work in the same way: they visit about:preferences#privacy and automate interactions with the interface there to clear the cache.
To use either script, simply use the clear_firefox_cache() utility found in either script.
See the evaluate-clear-cache.py script for a complete usage example (it assumes Firefox 61, at least).
You'll need to have geckodriver installed on your system (on Linux, this is done by installing it from your package manager) as well as Selenium.
If you're using clear_firefox_61_cache.py, make sure that you have Selenium version v3.14.0 or above installed.
You can install it globablly via pip with:
pip install --user seleniumor upgrade your existing version with
pip install --user -U seleniumThen, run the script with
python evaluate-clear-cache.py
