Firefox row height bug
There's a little bug which has appeared in the past few days or week I'm running todoist on Firefox 18.0.1 Mac. When you move the mouse over the tasks (in either day view or subcategory view but NOT in top level category that has subcategories), the row height of each task expands by a small amount, probably only 1px. As you move the mouse over the tasks you can see the tasks underneath all moving further down the page.
When you click the todoist logo to refresh the current view, you see all the tasks shift back up to their original position.
