To clear the browser cache for Mozilla Firefox, get started by clicking the Hamburger icon in the top right and selecting History.

In the menu that appears next, select Clear Recent History.

You can also access the menu by using the shortcut: CTRL + SHIFT + DEL. Firefox will then open a popup. In the Time Range to Clear dropdown, select the Cache option and anything else you’d like to remove from your browser’s saved files. You have options to remove the browsing history, cookies, search history, and data items like site settings and offline website data.

Use the Time Range To Clear menu to pick how far back you’d like to go when clearing out the cache data. You can choose the entire history or even just the last hour.

When you have all the options selected, click on the OK button to proceed. That successfully clears your browser cache in Firefox.

As an alternative (and to find a few extra browser cache settings), go back to the three-lined hamburger icon. Choose the Settings tab this time.

hoose Privacy and Security.

Under the Cookies and Site Data section, you can use the Clear Data button.

This is a little different from the previous method for cleaning out cache data.

You’re only asked about cookies, site data, and cached web contentwith this one. Furthermore, the popup window displays how much storage space you save with these deletions.

Click the Clear button to finish.

Also, back on the Privacy and Security page, you’ll see the following options:

• Manage Data.
• Manage Exceptions.
• Delete Cookies and Site Data When Firefox is Closed.

The Manage Data button lets you examine each stored data item to delete them one by one potentially. You can also go into the Manage Exceptions area if you’d like to exclude some sites from having their cookies or site data deleted from automated processes. Lastly, the Delete Cookies and Site Data When Firefox is Closed checkbox automates clearing your browser cache, but only when you completely shut down Firefox.

And while we’re in the Privacy and Security area, you should know that there’s another History section, similar to the one accessible from the Firefox hamburger menu icon. Here, you have a button to Clear History, which allows selecting what to delete.

There’s also a dropdown section to never remember the browsing history or customize your settings. Some may use that to automatically prevent the cache from saving data in the first place.

And that’s it! Your Firefox browser cache is now empty and potentially automated for the future.
