How To Clear Cache and Cookies in Firefox [All Devices]
Even though it is less of a resource hog compared to its peers, Firefox can still experience slowdowns on occasion. This happens when the browser’s cache becomes filled with files, and it is not limited to Firefox alone.
In this article, we will show you how to clear the cache and cookies in Firefox.
What’s a Cache and What Are Cookies?
The browser’s cache is a folder that stores temporary files from the websites that you visit. You may notice that during the first time that you open up a website it loads rather slowly. When you return to a website you have already visited, however, it takes considerably less time to open. This is because the various images, text data, and other webpage information, are already saved on your device.
Cookies, or an HTTP cookie as it is formally known, are bits of data that you enter on particular sites. It contains passwords, various inputs to text fields, mouse clicks, and other site activity information. This means that if a website records cookie information, you won’t have to enter passwords every time you visit the site. You will also notice that when you return to an online shop that you have previously visited, items put in the cart stay there. Those are cookies as well.
Why Do They Need to Be Cleared?
In general, cookies and the cache are convenient because they speed up the loading times of sites you visit often. The problem is that all that extra data in your drives slow down your device’s performance. Eventually, the time you save when you open frequently visited sites is negated by slower device loading times. Occasional cleaning of the cache is recommended to avoid this. You can either clear everything, or clear single files so that you free up space, but still, get to keep the data on specific sites that you open.

Is the Firefox cache and cookie data deleted permanently? Can it be recovered?
Technically, any file that has been deleted from your computer or phone is still there, just hidden. They will eventually be overwritten by new data as time goes by. Recovering these files is usually a hit or miss process. You can use recovery programs, or try to locate the files yourselves by opening the Mozilla Firefox folder on your device, but these are never guaranteed.
If you want to prevent accidental deletion of cache and cookie files, consider backing up your data every so often, Otherwise, just open the websites again to recover website data.
Keeping Firefox Fast and Resource Friendly
Firefox is a very fast and resource-friendly browser, but it may still experience stutters if you don’t routinely remove unneeded data. Clearing the cache, and removing useless cookies every now and then, ensures that Firefox keeps running at an optimal rate.
