Hi there.
Is my first day on an eee pc 700 4g surf --- os xandros and i try to update mozilla firefox and my flashplayer.
Can anybody tell me what version of firefox should i search for and how can i install it?

Simple answer: Xandros is outdated and not supported for years now, If you want recent software you have to replace that distribution with a recent and supported one.

I agree. The 701 is limited by the size of the internal SSD, but you can use an SDHC card as large as you can find and/or afford, and it will run about as fast as the slow internal SSD. I have a 701 set up as a server on my network, using an SDHC for booting, with a large USB HDD for storage. I also have a 900 which came with XP, which I kept, and run Debian from a 16GB SDHC on it. That works pretty well. With a larger SDHC, you can run any modern Linux distro on the 701 without problems. If you choose to keep Xandros, which was obsolete when Asus started selling the 701 years ago, you're pretty much stuck with the software that came on it, because of dependency problems with all the newer software.
