I have the same problem. The package "ubufox 0.6" installs the add-on "Ubuntu Firefox Modifications 0.6", and it disables all extra icons on the navigation toolbar. I have extra icons like: adblock plus, Feed Sidebar, ViewSourceWith, Downloadhelper, etc. I also have the TabMixPlus add-on, but I cannot find a specific problem with that add-on.
Solution: disable the Firefox add-on "Ubuntu Firefox Modification". Restart Firefox. Click with the right mouse button on the navigation toolbar to set the extra icons on the bar again. -- i cant add icons to my Navigation Toolbar https://bugs.launchpad.net/bugs/273020 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
