Firefox 108.0, after update 2 toolbar icons are missing

[hcsns]

Hi all,
just updated Firefox to 108.0 version and after the update 2 icons are now not displayed on the Tabs toolbar.

If I open "Customize Toolbar..." the 2 icons are there (new tab and list all tabs) when I close the Customize window the icons disappears again. Tried to remove the "new tab" and insert again but no effect.

Any clue?

It's my fault! My usercrome customization is the culprit!
