When I quit FF 33 it runs for anything from 30 seconds to several minutes before it actually quits unless I use Force Quit (Mavericks 10.9.5).
I've had this problem since FF 32. When I exit (via the Menu Quit command or by a right-click on the Dock FF icon) FF starts taking up a major percentage of all four cores on the iMac CPU and churns the disk doing something. This can take 10s of seconds to minutes, and I often have to force-quit in order to get it to stop. This also just happened on my MacBook Pro (also FF 33 and Mavericks 10.9.5).

Are you using "Clear history when Firefox closes" to clear personal data?
- Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
Yes, I've attached a screenshot of my settings. I've read various comments about problems with history clearing dating back to FF 29. Are they still not fixed? If not, are they going to be fixed?
Does this issue still happen if you do not use this feature to clear personal data or possibly exclude the cookies and let them expire instead when you close Firefox?
You can also exclude other items if removing the tick on cookies doesn't help.
