From jscher2000 - Support Volunteer answering my previous question: His response to me: Hi, do you mean the sidebar that you can optionally open on the left side (Ctrl+B) or the Toolbar you can optionally open below the address bar (Ctrl+Shift+B)? In another thread, someone mentioned there is a new option for the sidebar to "collapse" which I guess means to close itself, but that isn't happening on mine yet. Perhaps it is an experimental option that is currently in testing. To roll back your sidebar to the classic behavior, you could try the following: (1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk. More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future. (2) In the search box in the page, type or paste sidebar.revamp and pause while the list is filtered (3) If the preference is set to true, double-click it (or click the Toggle button at the right end of the row) to switch the value from true to false Any difference?

CLARIFICATION OF MY QUESTION: I checked the way you said and the sidebar.revamp already says false. What I am talking about is as follows: In the windows 10 we had, and using Firefox, there was the complete My Bookmaks list on the left side, from top to bottom. Those not showing I could scroll down through them. It also had a search bar where I could search for a sepcific bookmark. (I have had 2 strokes and I cannot remember things if I can't see it as I do it.) NOW, however, with Windows 11, there is a "tab" I guess you call it on the left end of the ribbon. If I click on that, the My Bookmarks expands down (like it did look before) and I can scroll down if the one I am looking for is below the shown part of the list. HOWever, if I go to type anything outside of that list, it collapses back to the tab. It also does NOT have the search bar for the bookmarks at all. So if I cannot remember where the bookmark is located (I have 95 bookmarks) I have to scroll down through most of them to find it. What I want is for the entire bookmark list to REMAIN visible or on top when I am doing other things. Ialso would like to be able to search for a specific bookmark which would bring it right up.
