What is a cache and should you clear it?

To understand what a cache is, let's do a quick exercise. Visit any website you haven't opened before and notice how much time it takes to load. Then, try to reload this website. You'll probably find that the second time it loaded faster.

When you visit a website for a first time, your browser downloads a bunch of data, including files, scripts, and images. It stores this data on your device to quickly load the website when you're revisiting it.

In short, cached data improves a user's experience, as websites load faster. However, there are several cases when we recommend clearing your cache:

You lack storage space on your device.
Your Mozilla Firefox browser is sluggish.
You want to get rid of private data collected by your browser for security reasons.

What happens when cached data is deleted?

A cache isn't crucial for the performance of your device or a website you're trying to open, therefore you can delete it whenever you want. However, be patient, as it will take more time to load websites with any empty cache. Once you've visited a certain website in Mozilla, the cached data will be saved again, and everything will work as normal.

If your browser was slow and your computer lagging, clearing your cache might solve this problem.
