Firefox bookmarks disappeared apparently per update 153 using Win 11 pro.

My Firefox bookmarks, tool bar, bookmarks menu, etc. all disappeared apparently due to update 153. As stated, I use Windows 11 Pro but my Firefox apparently is telling me that I'm on Windows 10. This makes no sense to me but that is how I'm reading my screen. I have no idea if the update caused the disappearance of approx. 900 business-related bookmarks what happened other than things were fine one day and then 18 hours later all was gone. I went through the well written article by "AliceWyman, Tonnes, Michael Verdi, scoobidiver, John99, Swarnava Sengupta, Jason, user669794, adampeebleswrites." I followed article text as best I could getting to my profile per the Application Basics, Open Folder and found three "sqlites." Here is where I get concerned because after following the article's direction, nothing happened. I apparently created a new profile per no. 153, but I also (apparently) have profiles back to no. 147 per a list I saw onscreen -- but I cannot seem to do anything with that information when I click on those folders. Articles tell me that I can revert back to a prior profile, but I cannot do anything with these prior profiles. At this point I'm fearful of doing anything more. What do I do now? The real question to me is whether anyone in the Mozilla support community knows of someone who can help over the phone or log in whether as a volunteer or paid consultant. The other question is whether Mozilla is capable of fixing this bookmark issue that apparently emanates from so-called updates. The articles appear to assume that Mozilla / Firefox have had this problem repeatedly in the past. If someone is aware to such a volunteer or consultant please forward the above and ask him/her to contact David at < [redacted email from community support forum] > Thank you all.
