Long time Firefox user. In the past couple of weeks, Firefox has become "laggy", sometimes displaying "not responding" when attempting to navigate to a different open tab and ultimately crashing out. I don't have the usual suspect extensions enabled so I'm not seeing what is causing this issue. Since 18 Jan 2014, the following crash reports have been created: bp-9aa1bef8-7d3d-420a-a5ba-c69452140131 31/01/2014 11:11 PM bp-f1969078-0f08-4f5a-8a62-a30dc2140129 29/01/2014 8:11 PM bp-77b22425-2acf-4f44-8755-bc46c2140127 27/01/2014 11:46 PM bp-affd0324-16a7-4001-8747-8f5342140126 26/01/2014 11:57 PM bp-823b764c-751a-48d2-9830-6a2892140124 24/01/2014 9:19 PM bp-cfa9fabf-9186-4751-ad1d-cf8702140119 19/01/2014 12:15 PM bp-6e0919c5-c4ee-42fa-80f1-a98922140118 18/01/2014 9:08 PM
