[solved]splash screen hangs(not the app) - how does the memory usage work?
I have been using Firefox portable 1.5.0.3 with winXP sp2 for some years, now. It always worked fine.
Last week, I got a virus from a streaming page. I knew it was a malware because of the sudden lag i experimented. I had to force the closing of Portable Firefox. I think I have got rid of the virus manually (CPU usage normal, network requests normal).
