Any reason you are sticking with Mac 10.9? It's old, insecure and unsupported by Apple.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can try to modify multi-process settings to see if this has effect.
- set dom.ipc.processCount to 1 if it is currently set to a higher value (4)
- disable multi-process windows in Firefox
You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.
- browser.tabs.remote.autostart = false
- browser.tabs.remote.autostart.2 = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
Try to disable IPv6 (check for other possible causes as well).
