Well I just upgraded to Firefox 2.0. It's great, I love it, lots of wonderful features. However, much to my chagrin, I have just discovered that I can no longer work in Google Spreadsheets!
It must be a new security feature that's causing the issue, but I can't edit any cells. I can only copy and paste, or use the buttons to change content. And then when I do, it says "updating…" forever, doesn't show the update, but then if I close it and re-open, the update has been made.
Anyone else experiencing this?
