if someone uses my wifi,can they see my facebook?

[Mad Scientist]

i have given my password to my uncle who lives downstairs..
i am sure that i logged out my facebook after some hours when i came back home and started my pc it was logged in.
and my pc has password so dont say someone accessed my pc..
and if me and him both are using google chrome..i.e. chrome for ipad and my pc so will it make any difference?

No, he can not. As long as he is not using your PC, and only he is using his device, not yours, then he cannot access your saved logins, passwords, etc. Unless if he is really tech savvy, like myself, and can intercept passwords and such through the network. Nevertheless, the only way theoretically that he could see your facebook is if he was on a VNC viewer connected to your PC remotely, but you would be notified if that was the case. You're okay! (:

Nope. If he is on a different computer, he doesn't have access to your search history, passwords, etc. My husband and I are on the same IP address and I can't affect what happens on his computer and vice versa

Coty Thomas add me, I can use your expertise !! but Coty is right, unless you have your setting on you PC as save my passwords, he can't see your stuff in Facebook. next time delete All your Searches before you log off!!
every time you log in on f acebook they ask if you want to save your password, I always click NO
