Customize no longer works for me in FF 29. It just brings up "about:customizing" in the URL box
I like the new interface in FF29, but my back and forward arrows no longer show in the toolbar. No problem, I thought. I'll just correct the lost customization. But when I choose customize, I don't get the usual customize menu. "about:customizing" is simply inserted in the URL box.

Have you tried it in "Safe Mode" - F10 > Help > Restart with addons disabled?
When I enter "about:customizing" it takes me to the same customising view as does using right-mouseclick on a non-active part of the main toolbar.
Another gotcha might be that at the bottom-left there is a drop down list where menus can have their visibility set. It's possible for some buttons to be hidden because these menus are set "off". Just for when you do find your customise page ...
I did try safe mode -- it didn't solve the problem. Clicking customize from either the menu or after righ-clicking in the toolbar just inserts "about:customizing" into the URL box.
