[ale] Browser cache maximum file size: Ubuntu/Linux Mint

[nolan.voight at gmail.com (Nolan Voight)]

Another one of those things which is staring me in the face, but I
just don't see it. Firefox is caching media such as videos in
~/.mozilla/firefox/{varies}/Cache/ and seems to have a file size limit
of 64MB. If I'm trying to save a video that's playing from the web,
that's where it stops saving. Where can I increase that file size
limit? Went to about:config, filtered for cache, increased any
numerical values there, but no change. Is it a Nautilus setting?
