How to Clear Cache in Firefox on Mac

Is your Mac running slow? Experiencing website errors? Built-up cache and cookies could be the culprit. Just like a cluttered home, your browser accumulates unnecessary files from frequently visited sites. While caching improves browsing speed, excess files slow down your Mac and cause glitches.

This guide shows you how to clear your Firefox cache on a Mac, both manually and automatically. Clearing your cache is safe and recommended for optimal performance.

Why Clear Your Firefox Cache?

Firefox, like other browsers, caches data (webpages, media files) to enhance your browsing experience. However, excessive cache slows your computer. Regularly clearing it frees up storage space and removes unnecessary data.

Manually Clearing Firefox Cache on Mac

Follow these steps to manually clear your Firefox cache:

1. Access Firefox Settings: Click the menu button (three horizontal lines) in the top right corner, then select "Settings" or "Preferences."

2. Navigate to Privacy & Security: In the left-hand menu, select "Privacy & Security." This section manages your online privacy and security settings.

3. Locate Cookies and Site Data: Find the "Cookies and Site Data" section. This is where Firefox stores cookies and website data.

4. Clear Data: Click "Clear Data." Select the data you wish to remove (including cache) and click "Clear."

Automatically Clearing Firefox Cache on Mac

Firefox allows automatic cache clearing upon browser closure. To enable this:

1. Open Firefox Settings, then go to Privacy & Security.
2. In the "Cookies and Site Data" section, check "Delete cookies and site data when Firefox is closed."
