How to Delete Browser Cache in Firefox - Firefox

Delete Firefox browser cache by opening the menu, selecting History, and choosing Clear Recent History from the dropdown.

Clearing Cache in Firefox

To delete browser cache in Firefox, click the menu button (three horizontal lines) in the top right corner. Navigate to History, then select Clear Recent History. A dialog box appears with multiple options. Ensure "Cache" is checked along with your preferred time range—select "Everything" to remove all cached data.

Click Clear Now to complete the process.

Keyboard shortcut: Press Ctrl+Shift+Delete (Windows/Linux) or Command+Shift+Delete (macOS) to open the Clear Recent History window directly.

Cache Settings and Automation

Firefox also allows automatic cache deletion. Open Preferences by clicking the menu button and selecting Settings. Navigate to Privacy & Security, then scroll to the History section. Choose "Firefox will use custom settings for history" and enable "Clear history when Firefox closes." This option automatically deletes your browser cache each time you exit the application.

The cache stores temporary files from websites you visit, including images, scripts, and data. While caching speeds up page loading, clearing it periodically protects privacy and frees disk space. Firefox version 148.0.2 supports these features across Windows, macOS, and Linux platforms.

Additional Options

You can also clear specific website data. In Settings under Privacy & Security, find "Cookies and Site Data." Click "Manage Data" to view and delete cache from individual websites. This selective approach works well if you want to preserve cache for trusted sites while removing data from others.

Recommendation: Enable automatic cache clearing if privacy is your priority. For users who prefer faster browsing, manually clear cache monthly instead. Regular maintenance keeps Firefox running efficiently without compromising your web experience.
