I cannot open the browser at all everytime I try and open it it comes up with crash reporter and then the browser doesn't open at all. I cannot open it in safe mode either as when I try and press shift while opening it it doesn't even come up with an option to open it in safe mode. I cannot troubleshoot it if it is not opening either which is frustrating. I have tried uninstalling and reinstalling but still no use.

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

  1. Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
  2. In that text field, enter %APPDATA% and press Enter. An explorer window should open.
  3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
  4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
  5. Open the most recent 5 files with a text editor and copy the IDs.
  6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Try to boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.

Here's one fix that worked for me: I just started having this problem, severely...... with Internet Explorer and Firefox. So I checked the video .dll files (my card is an ATI so I looked at all of the .dll files starting with "ati") in Windows > "System 32" folder, AND the Windows > System 32 > "dllcache" folder. After I looked at each ATI video .dll file's Properties I found the same named .dll files did not match!! I simply found the most current ones, then copied those and replaced the older ones.

Problem fixed!! It was crashing sometimes in seconds from opening Firefox OR Internet Explorer. Flash Player was constantly crashing too if the pages stayed open long enough for that to even run. Not anymore!!

These are the 4 crash reports that I found in the submitted file. These crashes have been going on for the past 3 days. I just got my computer back after having a virus destroy the hard drive and everything is fresh and newly downloaded. There are no viruses (I run avast) and there is no malware as I scanned it twice yesterday with Malwarebytes. Thanks in advance for your help.

Hi stmwnc

That is a problem with an extension (Apple Firefox DAV; iCloud) that has this file: AppleFFDAV.dll
