Firefox 74 breaks icons and bookmarks side bar

[roaminghawk]

Hi,

After updating to Firefox 74 Icons seems to be arranged horizontally and not vertically like before.

Before I had width set to 77% to accommodate a space for some icons before the bookmarks toolbar:
#personal-bookmarks {
height: 100% !important;
width: 77% !important;
transform: rotate(-180deg)!important;
transform-origin: 50% 50%!important;}

Before transform:

After transform:

Without bookmarks toolbar:

The add-on icons seems to be arranged after the bookmarks toolbar.
Sorry if that seems vague.

Thanks

Of course I'm reporting an issue with the code for vertical toolbars.
It won't show add-ons icons probably with the bookmarks toolbar.
