Same problem with Awesome screenshot and Ad-block+

Greasemoneky, however, persisted.

Unfortunately, the last so-called upgrade took away some things that we, the users, want and need. Some add-ons are no longer compatible with the new Firefox. For one thing, the add-on bar at the bottom of the window was removed. And since there are many add-ons that use it . . . . .

Many of us are using Classic Theme Restorer (Customize Australis) {web link} Restore squared tabs, appmenu, add-ons bar, small button view and more on Australis UI (Windows/MacOSX/Linux + Fx 29+).

As to the missing icons, they might have been moved to the address bar, or back to the icon bank.

Move your mouse to the top of the Firefox window, then right click. You will see a menu of the available toolbars. Select Customize. In the new window, look for the icon. When you find it, hold down the left button on it, and move it to where you want it to be. You can move any of the icons you want from here, but some icons are locked in place.

Super. That did it! Thank you. All these hidden "mysteries!"  :)

Glad to help.  :->
