Firefox 3.6.20 received the same security updates as Firefox 6.0 did. Firefox 5.0 isn't supported any longer.

Do you even have a Pentium 4 SSE2 processor? Most P4's came with more than 256MB of RAM.

I have a hunch that old WinXP PC isn't strong enough to run a Firefox 4+ version. Firefox 3.6.20 just might be the final version you can use.

Thanks Ed Meister ... I just hope the 3.6 doesn't dissappear as 5.o .. for those attached to their P3 .. haha.

But I still keep curious .. how much ram does version 6 occupies. Thank you Ed any way.
