Is It Just My Computer or anyones...?

Well im not sure if this is my computer or if its just something that happens or what ever but when i type in the letter ‘s’ in the address bar in firefox (havnt done it in IE) and then press enter or the go button, it starts loading the mcdonalds website??

Can someone else test this for me on there comp, dont type any HTTP or WWW. crap, just put an ‘s’ in there (with out quotation marks) and press enter.

I know this is LAMO but im just curious!
