Firefox chrashing when customizing toolbar.

[Ravi5kumar]

I recently updated to Firefox 16 and facing the problem. Whenever I open customize toolbar window and drag a tool to the toolbar the whole Firefox hangs! Anyone experiencing this problem? Any fix for that?

Open FF in safemode (run the command firefox --safemode) and try customizing the toolbar. If it doesn't crash, then the problem is one of your addons. Disable them all and re-enable them one by one until it starts crashing again, and you have your culprit.

Thanks dniMretsaM! The real problem was one of the addon that causing the crashing! The culprit was the addon named 'Smartest Bookmarks Bar 1.1'. I disabled it and now Firefox no more hangs when I customize toolbar...
