There was this important website that I had and it was in my history, but then I dunno wat happened but my whole history was deleted. I didn't do it. I am using a firefox. and I have a windows xp. Do you know how I can get it back?

Firefox has a History.dat that most likely was not deleted. Windows cannot open .dat files. This program can:

Be sure to choose the view option rather than delete.

Will this let me view what I have deleted?

Most likely. The reason that this program was developed is that all browsers have .dat files.

When you delete your internet files you do not delete .dat files. They are sometimes referred to as secret files.

You cannot delete .dat files with Windows (nor view them). Without secret software.

The developers of this program did not like that idea. Give it a try.
