How to make /tmp in RAM?
How to push the cache of Mozilla Firefox, Opera browsers there?

Answer 1

You should not think that browser developers are idiots. Browsers have a cache in RAM, what gets into the disk cache is that it makes no sense to keep it in RAM.
Also push the swap into the RAM... (yes, on ancient 32-bit machines with PAE, this was a way to use memory above three gigs, but we are not in a museum of computer technology).

Answer 2

For example:
/etc/fstab:
tmpfs /home/$USER/.cache/google-chrome tmpfs noatime,nodev,nosuid,size=512M 0 0

Answer 3

Use Profile-sync-daemon

Answer 4

$EDITOR /etc/default/tmpfs
