Cmd+Shift+E not working
I think I might have found a bug where Firefox' own shortcut cmd+shift+E (tab-groups) stops working – even clicking on the icon in the navigation-bar won't open the tab-groups. It occurs when the option "try to overwrite conflicting shortcuts" (I am on a german system so this is my translation) in Zotero's preferences is active. It is strange, as I don't have E assigned to any of Zotero's shortcuts. Can you recreate this?
