Hello, About a month or so ago, I noticed the New Tab "+" button was missing on the right hand side of the tabs bar. Also missing is the "arrow" for clicking tabs rightward (the left "arrow" for clicking tabs leftward is still present). After a Firefox update today, I had hoped it would come back but it is still missing. I opened "customize toolbars" and clicked "restore defaults" but the New Tab "+" button is not listed as an option! Is this yet another bug that Mozilla claims is a "feature" that no one asked for (like erroneously moving the tabs bar to the top)? Thanks.
