If something goes wrong with your browser, one tried and true troubleshooting method is to clear its cache, where information from the websites you visit is stored so you don’t have to load it all again upon repeat viewings. The cache can sometimes get too full and cause storage problems, but luckily clearing the cache on Firefox is an easy process.

To clear Firefox’s cache on desktop:

1. Click “Application Menu” in the top right corner, then click on “Settings.”

2. Click “Privacy & Security,” and under “Cookies and Site Data,” click “Clear Data.”

3. There are options to clear “Cookies and Site Data” and “Cached Web Content.” Choose both and click “Clear.”

To clear Firefox’s cache on mobile:

1. In the Firefox app, tap the menu icon in the bottom right corner, then tap “Settings.”

2. Scroll down to the “Privacy” section and tap “Data Management.”

3. You can select multiple types of data, but to clear the cache, turn on the “Cache” option, then tap “Clear Private Data.”
