All buttons, or one specific button? If only one, which one?

all buttons. I think i find out the problem, we cannnot just drag and place. must right click and select menu or tools bar, the ok. it is ture? BTW, cannot place the button to bookmark tools bar now.

Please see this support article.

I know it, but when I drag to the menu to drop, there is a stop sign (like O with slash in it ) above the icon and I have no way to drop. why?

test again today, it is working when I am using a default profile use for FEBE restoration. because of profile or add-on installed before? any ideas from your guys?

Some icons are locked in place.

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+).

This will restore many of the things the last upgrade took away.

all icons are locked. hit the Restore Defaults, it is not working, still not working. must I use a fresh profile? any way to restore Nosquint database?

You can check out the settings of the CTR extension via its Options/Preferences button on the "Firefox/Tools > Add-ons > Extensions" page. You can find extra toolbar buttons and more toolbar settings in Customize (3-bar Firefox menu button > Customize)

read the artical above and problem is not solved. my question here is that:

I cannot drag the add=on button and drop, it seems locked. must I create a fresh profile to solve this issue?

• Start Firefox in Safe Mode {web link}

While you are in safe mode; Press the <Alt> or <F10> key to bring up the tool bar. Followed by;

Windows; Tools > Options Linux; Edit > Preferences Mac; application name > Preferences

Then Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites and see if there is still a problem. Then restart.

Make sure that toolbars like the "Bookmarks Toolbar" are visible.

• Firefox menu button > Customize > Show/Hide Toolbars
• View > Toolbars (press F10 to show the Menu bar)
• Right-click empty toolbar area

Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.

• check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar
• if "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the Customize palette into the Customize window to the Bookmarks Toolbar

• if missing items are in the Customize palette then drag them back from the Customize window on the toolbar
• if you do not see an item on a toolbar and in the Customize palette then click the "Restore Defaults" button to restore the default toolbar setup

finally find out the problem. the problem is due to add-on: Hide Menubar, every thing is fine.after remove the add-on.

thanks for the help from your guys.
