Extensions and Styles buttons not working in FF ESR 140.5

[jondamvi]

FF devs as always just carelessly rename things and break compatibility even on ESR.
Buttons Extensions and Styles not working anymore.
Is there a fix?

By not working I mean that these buttons not showing in main UI as icons, they disappeared.

Not having any problems here with 140.5, try this:

rebuild_userChrome.uc.js.zip

Same thing here on Waterfox (140)
