Several have been mentioned in previous tests but the one that annoys me the most is that in Chrome when I click on the info tab for a player I meet in-game, the act of going to that player's profile page throws me out of the world, forcing me to reload to resume play.
This doesn't happen in Firefox, where the action has the player profile open in another tab.
I'm clicking on "player info" to discover level, if this a new player, someone who might need help, or someone who has be alpha testing for months and is likely to be insulted if I offer to help them make salt.
I also don't want to go around asking " you new?" all the time; sounds like a lame pick-up line.
