Bookmarks Sidebar randomly goes blank in Firefox 94.0.2 (64-bit) in Win 10
I keep the bookmarks sidebar open.
Sometimes when I have been working in other programs and return to Firefox, the Bookmarks sidebar is empty except for the Bookmarks Toolbar, Bookmarks Menu, and Other Bookmarks headings.
When this happens, the sidebar is unresponsive.
Closing and re-opening (ctrl+b, ctrl+b) the sidebar restores everything to normal.
Any help with this issue would be appreciated.
