Hi, Please check if this happens in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode]. Safe mode disables the installed '''Extensions''', and themes ('''Appearance''') in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons'''. Hardware acceleration is also temporarily disabled - the manual setting is '''Tools''' > '''Options''' > '''Advanced''' > '''General''' > [https://support.mozilla.org/en-US/kb/Options%20window%20-%20Advanced%20panel?as=u '''Use hardware acceleration when available''']. All these settings/options/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme, option or hardware acceleration is causing issues. Disabling/enabling hardware acceleration, and some types of add-ons in normal mode may require a Firefox restart.

Thanks dum, I'll give this a shot later. I was wondering if this feature was removed from FF13. Can you right-click and and see the dialog box when you choose "Bookmark page", just want to make sure other people have or don't have this option.

Yes, it's the same dialog box with the folders pane, as in the previous version.

Hmmm, good to know. Will try safe mode trick and see what happens.

Thanks for all your help. It was an extension causing the conflict, "Compact Menu 2". It's disabled and the dialog box is back. :)

You are welcome :) Thanks for posting the helpful info.
