Todoist slow in Firefox
I've been using Todoist in Firefox for a long time, but lately it seems like it's slowing down my entire system. When I have Todoist open in my browser, my Firefox CPU % usage spikes and the system starts to hang when scrolling through tasks or checking them off. When I close Todoist or run it with Chrome, the issue seems to go away.
I'm running Mac OS X 10.8.5, Firefox 24.0, and Todoist Premium.
