How do I get rid of this thing (see picture)?

If you have Adblock, you could install the Element Hiding Helper extension. You could also just not click that button though ;-)

Also, I don’t think that other person was a troll: it seems like a feature to find players you don’t know that are at about your skill level. The other player has probably pressed the same button.

I knew I shouldn’t click it, but I was hoping it would come up with some way to get rid of it.

It appears that “smart match” is a feature they added with the recent version of WWF. It also looks like it is permanent and there is no way to get rid of it. Sorry.

@Dutchess_III That’s why I also mentioned Element Hiding Helper, although it only appears to be available for Firefox :)

Installed @Vincentt! Thanks!

So did it work? I’m not sure if it’s clear enough how to set it up :)

No. But a “hide” button now comes up on other things. I’ve learned to ignore it.

Also, I have yet to restart my computer. When I do, that may make a difference.

Ha, the “Hide” button is AdBlock’s, I think you can disable that with the option “Show tabs on Flash and Java”. To hide the button, visit the page with the button, go to the Tools menu of Firefox, then mouse over “Adblock Plus” and click “Select Element to Hide”. Or follow these instructions.
