How to save a file locally on the frontend?

Question

JavaScript

How can you cross-browser save files taken by URL (up to 10mb) on the client for quick access to them when reloading a web application?
I dealt with the FileSystem API, but it is only for Chrome.
Minimum required: Chrome, Opera, Firefox.
