Why should you clear cache in Firefox
“Cache” refers to all the data on web pages viewed through a browser. The cache stores information about images, videos and other website content. It helps to make your browser run faster. If the page you want to view is already in the cache, the browser instantly downloads it from your hard drive. At the same time, over a period, cache files take up significant disk space and, as a result, slow down the Mac’s and browser’s performance. Use one of the options below to clear browser cache in Firefox.
Important notes about clearing Firefox cache:
- After deleting cache files, you will have to log in again to your accounts on different websites. Removing the cache deletes the autofill information and logs out your accounts.
- You can remove cache right in the Firefox preferences by finding these files manually in the Library folder. However, the quickest way to remove the cache of any application on Mac, including the Firefox browser, is to use App Cleaner & Uninstaller.

FAQ about clearing the Firefox cache
What is Firefox cache?
Firefox cache files are temporary files with the data about your websites’ visits. All this data is gathered by your browser and stored on your Mac. Cache files help to provide a quick page load the next time you visit a website. Also, thanks to the cache files stored on your Mac, you don’t have to log in to a website account each time you visit it. This data can be auto-filled so you will be automatically logged in to your account.
When should I clear the Firefox cache?
Over time, Firefox cache files can accumulate and take up a lot of your disk space. Clearing the cache will thus help you free up space on your Mac. Another reason to clear the Firefox cache is to prevent errors on the websites you visit. If a webpage was updated, you can see the wrong old information on the page because of old caches. Sometimes, you can even face issues when a page is not loading. Clearing cache will help to fix page loading issues. Also, clearing the cache will make your browser work again smoothly.

Is it safe to clear cache on Mac?
There are two types of caches: system cache and user cache. The system cache is the data created by macOS that ensures correct Mac performance.
