I keep accidentally "liking" stuff here on Facebook!

It shows up on my Facebook page that I "liked" something on this site, which I had no intention of "liking". I need it to stop happening! Is there any setting I can change (either on Facebook or here) that will prevent this from happening? I know that if I stay signed out of Facebook it will stop, but I'd like to avoid that if possible, especially on my phone because it's hard to sign in on that thing. I was hoping Facebook would have a privacy setting I could change. Help!
