Firefox keeps crashing when I go to youtube, google maps, or even when I try to go to about:support. I tried to install your troubleshooter below and I got the same "Firefox stopped working" message as I did when I tried to go to the other pages. Here is what the event log says: Faulting application name: plugin-container.exe, version: 33.1.0.5423, time stamp: 0x545c0a59 Faulting module name: mozalloc.dll, version: 33.1.0.5423, time stamp: 0x545be5ee Exception code: 0x80000003 and Faulting application name: firefox.exe, version: 33.1.0.5423, time stamp: 0x545c0a37 Faulting module name: ntdll.dll, version: 6.1.7601.18247, time stamp: 0x521ea8e7 Exception code: 0xc0000374 Fault offset: 0x000ce753 Faulting process id: 0x163c Faulting application start time: 0x01cffee4690e539c Faulting application path: C:\Program Files (x86)\Mozilla Firefox\firefox.exe Faulting module path: C:\Windows\SysWOW64\ntdll.dll Report Id: 04b7b21a-6ada-11e4-a3e6-082e5f98acef and Fault bucket 634541599, type 17 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: firefox.exe P2: 33.1.0.5423 P3: 545c0a37 P4: StackHash_46b2 P5: 6.1.7601.18247 P6: 521ea8e7 P7: c0000374 P8: 000ce753 P9: P10: Attached files: C:\Users\Anna Rose Mahoney\AppData\Local\Temp\WER787C.tmp.WERInternalMetadata.xml These files may be available here: C:\Users\Anna Rose Mahoney\AppData\Local\Microsoft\Windows\WER\ReportArchive\AppCrash_firefox.exe_a4de22f67e2fff0176151125c4ed4a28da7af5a_04ca98f7 Analysis symbol: Rechecking for solution: 0 Report Id: 04b7b21a-6ada-11e4-a3e6-082e5f98acef Report Status: 0
