Rated 5 out of 5 stars

Yes, really a pity that Oleksandr is not interested anymore to update his great add-on. For Thunderbird I use now Menu Filter, for Firefox is nothing as good as Menu Wizard! But maybe the autor must stay at home now (because of corona) and will find time and energy to make Menu Wizard working on FF 68+... Wish him and his family all the best and good health!
