It appears you have an extension listed with

Extension ID firefoxdav@icloud.com
Version 1.4.14

That is involve in the crashing thread. Try specifically disabling or uninstalling that.

I am not Mac user an am not yet sure exactly what that extension is called.

I disabled the iCloud one. I went to the safe mode, it's works without crashing.

I have another one,

Some of your crash reports weren’t sent to the Mozilla Servers.

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it and select Submit.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.

OK so it works without crashing when it it is in safemode, so that is progress.

Try not in safemode but with icloud one disabled, does that work ok ?

No, i have iCloud notifier removed

the report ID is: e8c9b35a-4f12-494a-8e0b-6a6022150528

Still a problem with iCloud.

• Firefox 38.0.1 Crash Report [@ appleffdav.dll@0x44c8 ]

The bug report mentions iCloud Bookmarks, so try to remove that extension

• bug 1097138 - startup crash in appleffdav.dll

Yes, it works with disabling iCloud Bookmarks. Thank You,

I guess that i'll be using that desktop version of iCloud than this extension.
