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. On the keyboard, press [Windows] The image "Windows key" does not exist. + [R]. This should bring up a Run window that contains a text field.

1. In that text field, type %APPDATA% and press Enter. An explorer window should open.

1. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.

1. 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.

1. Open the most recent 5 files with a text editor and copy the IDs.

1. 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.

I apolagise you have already completed the steps at the top (call it force of habit)

If you have recently installed or updated any software, mainly from apple I would uninstall that first and see if it fixes the problom.

If not then re-install firefox itself and see if that fixes the problom

Hope this helps Brad

Thinking "apple" I turned off the external component "Bookmarks iCloud" (I don't know what it's called in English) and now no crashes. Too bad because it is a very useful component and with little competition (if any).

Sad to see software conflict but nice to see you back on your feet Happy Surfing :)

I don't understand how it came to be incompatible. She was born in version 35 but not right away. I don't know when it was updated extension iCloud but it makes me weird ..
