Is this what you mean?

Customize Firefox controls, buttons and toolbars {web link}

Type about:customizing<enter> in the address bar.

Note: about:customizing is no longer present in Firefox 47+ releases.

• Press Alt or F10 to bring up the Menu Bar.Then View > Toolbars > Customize.
• Right-click on a blank spot in the toolbar and 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.

There is also a Restore Defaults button at the bottom right.

It's about moving "Extension" icons. With your reply is my problem not solved. I'm sorry, please give me an explanation again.

I think you are talking about how the home page is set up, yes?

You should be able to reorder icons added by an extension in customize mode.

Dear Cor-el,

Thank you for responding and answering my question. You have helped me out gratefully! Your answer is right, easy to understand and to fulfill. I can move those icons from now on. Hereby I have an other question. I have more extensions added, but not all of those icons are shown in the toolbar. How do I realize that?

Real example I have in the toolbar 4 extension icons but I have 7 extension enabled. Where have been those other 3 icons?

Regards,

Van Lieren

Some extensions integrate into the right-click context menu or into the address bar, rather than the toolbar. Can you confirm on the Add-ons site how the missing ones are supposed to integrate?

What add-ons are you talking about? As jscher2000 said, they may not have icons on the toolbar. Just the right-click menus.

Also note that buttons might be moved to the overflow area (try full screen) and may not even be visible in customize mode when the window isn't wide enough (not sure if that is a bug).

Dear Cor-el, / Customer Happiness Team,

Hereby my question again. Please reconsider again, see attachment beneath.

Hi Van, your toolbar buttons are: AVG, Adblock Plus, ImTranslator, Grammarly and Zenmate.

You can learn more about the others on the Add-ons site:

https://addons.mozilla.org/firefox/addon/google-scholar-search-engine/ - the screenshots show its icon in the row of icons at the bottom of the address bar drop-down when you are entering a query (like other search engines), and also a new right-click context menu item

https://addons.mozilla.org/firefox/addon/to-google-translate/ - "This extension creates a context menu item in Firefox."

https://addons.mozilla.org/firefox/addon/wp-theme-and-plugins-detector/ - in the screenshot, it says the icon appears in the address bar (not the main part of the toolbar) only on pages made with WordPress
