You're (obviously) right - it was /tmp (where firefox appears to have stored quite some data).

While watching a video under firefox, I experienced what appeared to be a halt of the system: the system no longer responded to keyboard/mouse (no keyboard led activity), or to the network. As I have a RPi connected to the serial port, I logged in there to find that it was logging a lot of uvn_flush output: uvn_flush: obj=0xfd838db602e8, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0x0, offset=0x0. error during pageout. uvn_flush: WARNING: changes to page may be lost! uvn_flush: obj=0xfd838db602e8, offset=0x1. error during pageout. uvn_flush: WARNING: changes to page may be lost!
