I can't figure it out. No matter what I do, clicking on the smilie icons won't work for me but if I enter say ; ) without the space...
I cleared local cache, rebooted, started Firefox in Safe Mode (all my add-ons disabled), uninstalled Firefox and re-installed FF 17.0
No go... Icons on other sites work, seem to be just this one. I brought it up in IE just to see and they work there but that's no where even close to a valid reason to use that POS. I guess I could always revert back to 16 and see if it works there. Maybe I should try that.
Strange, especially since it works fine for others at 17.0
