That's really helpful, thanks. So it looks like there still might be some issue with Safari that we need to have a look at. It's difficult to keep up with all of the different browser quirks sometimes! Glad you can contribute via Firefox for now anyway.
Also, if you want me to merge your old account into your new one just send me the two usernames (and specify which is which). We could then link any contributions you made with your old account to your new one. Wouldn't want you to feel like you've lost any contribution points
