Extensions not displaying on toolbar or in customizations
My problems started after the upgrade to 113 when Firefox would no longer load at all. I tried deleting and reinstalling, but nothing changed until I moved the profile (yeah profile mgr didn't work either). I finally got it to reinstall and ran sync but had to also reinstall my extensions/addons. The extensions appear to be working, but the are not displaying in either the toolbar area or in customizations.
I have tried searching all over and different solutions but thus far nothing has worked. That includes right clicking on the extension and selecting to add it to the toolbar.
I repeat, the extensions appear to be working though I cannot call some of them up (EverNote for example), and I need Lastpass on the toolbar for password generation and to access the vault.
Extensions ARE displaying in Chrome browser.eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Attached is image of customization scree that also shows toolbar area. No addons anywhere.
Chosen solution
Firefox 109 comes with the Extensions button in the Navigation Toolbar as the new way to manage your extensions. The panel that opens if you click the Extensions button (puzzle piece icon) serves as overflow area for extensions you install. The legacy chevron (>>) overflow area still exists but is only used for built-in toolbar buttons as found in the Customize page.
In the Extensions button panel, you can click the gear icon 
next to an extension or use the right-click context menu to pin the extension to the toolbar (Pin to Toolbar).
To (re)move the extension from the toolbar back to the Extensions button panel, you can use "Unpin from Toolbar" in the right-click context menu.

Thanks very much, cor-el. I've been pulling my hair out with this one.
