How to Clear Browser Cache: Firefox Cache and Cookies

To keep your browsing working in top condition every time, it’s an essential step to clear Firefox cache (and cookies) so new information or updates from the websites can load and be viewed properly on your end. 

The cache and cookies are temporary files created by your Firefox browser as soon as you launch it. Since these files can grow quite big over time, you must clear Firefox cache regularly to also help save some disk space on your device.

Take a look at these easy steps to do it:

Note: Saved passwords, browser histories, and website login credentials may also be cleared while performing a clear cache. Make sure to have a copy of your logins and passwords, or bookmark your preferred links before proceeding to clear browser cache.

 

1. At the right side of the address bar, you will see three lines. Click on it for the Firefox menu to show up.

For those of you who would like to clear cache automatically once the Firefox browser is closed, you can tick on this checkbox: Delete cookies and site data when Firefox is closed. This way, Firefox always starts afresh whenever you launch.
