Hmmm, this creates quite a dilemma for me. I have 2 computers, one is a PC without the internet and one is a laptop (old and about to die) with the internet. My trial version is currently on my laptop but if I ever get FF I would prefer to put it on my more reliable PC, but I would still be in favor of submitting new filters via my laptop or something... I guess if I absolutley must I can just post the ffxml file online and give a trusted user my password, that way they could submit the filter for me, but that would be a hassle.
