Comment 3 for bug 560859

Yes I checked that but the program that used the most memory was "Alarm Clock" which used ~40MiB and it was the only program running, not even Empathy was running. After I closed Alarm Clock 0.05GiB of space on my swap partition freed, going to 1.55GiB used, and than I was able to start Firefox, which then used the free swap space leaving RAM alone (same usage as before I launched Firefox). When I tried to launch Firefox when swap space was full it just crashed on startup, which took a considerable amount of time (~30-40 seconds). Hope this helps.
