The browser also records network cache storage and displays the entries and sizes used on the local disk and system memory.
In this guide, we have shared the steps to view the cache size and clear the occupied storage from the Mozilla Firefox app.

Clear Cache Storage
Cache storage data reduces the webpage loading time by rendering the most used assets from the browser. However, if the cache storage space exceeds the limit, it hampers your browser’s functioning.
If your browser crashes, deleting cache files can help fix the issue. Follow these steps to clear the cache:
- Launch Mozilla Firefox on your computer.
- Click on More for the menu list.
- Select the Settings menu from the list.
- Switch to the Privacy & Security tab and scroll down to the Cookies and Site data.
- Click on the command button.
- Enable the checkbox for the Cached web content option.
- Hit on the command button.
It will clear the cache storage of the browser.
If you go back to the about:cache page, you will notice the cache storage size is significantly reduced.
You can also delete the Cookies and Site Data within the Clear Data dialog box to fix the issue with cookies data, but it will get you logged out of websites you’ve signed in to.
