I've had my tablet for quite a few months now but I don't really know how to do anything other than use the internet and play the games that come with it.

The problem I'm having is that scripts don't seem to work, for example the ones on Facebook to send messages or post comments, and in Wordpress to post an entry.

Could it be that my browser needs updating? If so, could someone instruct me on how to do that? I've tried looking everywhere but I can't find any explanations on how to upgrade things except for on their main site but they assume you have a PC. I have a mac.

Any help would be greatly appreciated.
