How to clear cache in Firefox

The Firefox browser, like any other web browser, saves HTML and media files to its caches. In most cases, cache helps to speed up the page loading time. Nevertheless, a large number of cache files tend to slow down the browser or to display some pages incorrectly if the information on the site has been changed.

Thus, you may need to clear cache in Firefox for different reasons, for example, to solve certain browser issues or to free up memory on your hard disk. In this article, we will share on how to clear the cache in Firefox.

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.

FAQ about clearing the 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.

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.

By default, the Firefox cache files on a Mac are stored in the following locations: Macintosh HD/users/user[ ]/Library/Caches/Firefox and Macintosh HD/users/user[ ]/Library/Caches/Mozilla

To get to the Firefox caches folder, open Finder → press the Cmd+Shift+G shortcut → type

/Library and hit Go → select the Caches folder → find the Firefox and Mozilla folders there.

On Mac, the browser’s cache is located in the hidden Library folder. To remove the browsers’ cache, you have to go to the

/Library/Caches location and manually select and remove the folders which contain browsers’ caches. However, you can also use third-party apps, like App Cleaner & Uninstaller, to effectively remove browser caches simply in two clicks.

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. If you want to clear the system cache, make sure that you understand how the macOS system works and what certain files are used for. Otherwise, you may erase the important files and damage your system.

User caches are temporary files created by an application that helps it load faster. Generally, clearing cache is safe. When you run an application next time, it will automatically create new cache files.

You can clear caches on Mac manually. However, the safest way to do this is to use a special utility, like App Cleaner & Uninstaller.

How can I clear a single site from the cache in Firefox?

In Firefox, I occasionally need to clear my cache to fix a website. But clearing the entire cache seems like extreme overkill. Is there any way to just clear the one site from my cache?

Note: This will clear saved passwords for the site as well.

If you want to do a force-refresh, which is what I think you want to do, hit CTRL+F5. And of course, Cmd+F5 on a Mac. Works on Chrome too.

Please note that there is currently no way to clear cached HTTP redirects (at least 301 type) without using a plugin.

Ctrl + F5 / Cmd + F5 does not work as you are being immediately redirected to the target URL so you can not refresh the original one.

So I used CacheViewer plugin mentioned here before to deal with this.

See also this bug in Firefox for details and possible progress on this issue.

There is no built in way to clear the cache of specific pages/sites in Firefox. You can «Forget about this site» which cleans the domain from history, you can «Delete this page» which cleans the specific page from history, but you can’t clean up single cache items belonging to a page (apart from going to your profile folder and deleting them).

There may be addons to do this, but I didn’t find anything when looking through them. Built-In functionality for cache deletion seems to have the all-or-nothing policy.

One day when you have not opened anything else, go to Tools ⇨ Clear recent history and then select to only clear the cache and then only from today or Xtime. Because you just visited the website, it should have moved its timestamps in the cache to the top of the list so you can just wipe all cache from Firefox for that day and thus clear the cache for your specific website.

There’s a similar question and answers shortly are:

In what seems to be a just released Firefox extension, the original question now has an answer which is both a direct solution to the problem posed (not how to also remove cookies, passwords, etc from the selected domain which happens through the use of «Forget about this site») and will handle websites which utilise a page redirect rather than a page content change that is undesirably cached. Great design also. Quick and efficient.

Looks like they might of changed a few things. I found the following:

While not removing all the site data, this handy addon will remove the cookies for the current site:

If you know the exact list of URLs that you need to clear from the cache (e.g. the corrupted CSS entry/ies from the site in question), you can clear them using this script (adapted from DoomEntry.js; needs to be run on the Browser Console ( Ctrl + Shift + J ), not the Web Console ( Ctrl + Shift + K ):

Simply run the script with each URL that you need to purge (or make up a loop. you know the drill).

Theoretically this should clear cached AJAX responses, other asynchronously loaded resources, and 301 redirect entries as well (as long as you enter the original (pre-301) URL).

Clear Browsing Data is a recommended Firefox extension which enables you to delete browsing data, such as cookies, history and cache, directly from the browser toolbar. The toolbar button can be configured to clear all browsing data with a single click, or to show a list of data types available for clearing.

Supported data types:

just open the same page in a firefox «private window» should work to refresh cache for that session and pull new page

Как очистить кэш в браузере Mozilla Firefox?

Кэш — это хранилище данных, расположенное в памяти компьютера, которое предназначено для быстрого доступа к скачанным ранее файлам с открываемых сайтов без повторного обращения к серверам этих сайтов, что позволяет значительно ускорить загрузку их страниц.

Очистка кэша при выходе из браузера

Чтобы кэш очищался каждый раз при выходе из Firefox, необходимо снова зайти в настройки, перейти в раздел «Приватность», в подразделе «История» выбрать опцию «будем использовать ваши настройки хранения истории» и установить галочку «Удалять историю при закрытии Firefox» и нажать кнопку «Параметры»:

What Is the Firefox Cache?

The Firefox cache contains locally saved copies of web pages you visited recently. This way, the next time you visit a page, Firefox loads it from the saved copy, which is faster than loading it again from the internet.

Clearing the cache in Firefox doesn’t need to be done every day, but it can solve or prevent certain problems. If the cache doesn’t update when Firefox sees a change on the website or the cached files are corrupted, it can cause web pages to look and act strangely.
