## What is it?

Firefox’s disk cache for each profile: images, scripts and pages from websites you visit, in `~/Library/Caches/Firefox`.

## What happens if you delete it?

Rebuilt as you browse. Bookmarks, passwords, history and cookies are stored in your profile in Application Support, not here.

## How to remove it properly

In Firefox, open Settings › Privacy & Security › Cookies and Site Data › Clear Data… and select only the cached web content option. Or quit Firefox and move the folder to the Trash.
