thanks, this appears to be an issue with an old "Facebook Photo Uploader" plugin - you can try to remove it like described at https://www.ehow.com/how_11399690_delete-upload-pictures-facebook-mobile.html

this crash will be fixed in firefox 34, which you can get right now as beta version from https://www.mozilla.org/firefox/beta/

Wow thanks a lot. I use firefox 34 now, and it works. So, I need to stick with this version or I can updated it when it tell me to update. By the way the article that you can to me it show how to remove from movie version right? but I use it with my MAC. So, is it the same?

PS. I appreciate your help.

yeah, sorry the article i've linked to doesn't appear to properly address the issue at hand...

here is a nother description on how to remove the plugin on a mac:

"Older versions of the Facebook (Photo Uploader?) plugin "fbplugin" will cause Firefox to crash, often on browser startup, on Mac OS X 10.10 Yosemite. To resolve, remove the file fbplugin from user Library (~/Library) Internet Plug-ins folder, which is hidden by default - see Show hidden files and folders." _{source. http://kb.mozillazine.org/Firefox_crashes#Plugins}
