Always open Sidebar when opening Firefox

I used to have the bookmarks sidebar open whenever I open Firefox. Now Firefox always opens without the sidebar. I have to click on the sidebar icon every time I want to open the sidebar. The sidebar stays open when I open new tabs. But when I close then open Firefox, the sidebar is not there. Must be a change with one of the updates. Is there a way to set the sidebar to always open when opening Firefox? Maybe in about:config?

You can try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
