I don't use the FB app either. I go to the website. I don't have any trouble on my laptop, but when I try to use FB on my Galaxy Tab, I get error messages saying the certificate is invalid, unsafe, etc. Also when I try to type a message or make a selection of one of the options, instead of just selecting that dropdown or whatever, it takes a whole large area and goes bonkers. I tried it both with Dolphin browser and Internet Explorer and both do it--but only when I'm using the tablet, not my laptop.
