I updated my Firefox browser to the latest version (133.0.3) and lost all of my bookmarks (there were so many). This has never happened to me with previous Firefox updates. How do I get these bookmarks back? I am devastated right now and really want my bookmarks back. Please help.

UPDATE: I read several previous questions and support about recovering lost bookmarks prior to posting my question. None of them applied or worked in my situation. This latest update version 133.0.3 overwrote everything in my local Mozilla folder and my old profile did not seem to exist anywhere, but after much searching I did eventually finally find the last bookmark file (after selecting to view hidden files, searched for places.sqlite in my C drive) on my computer from before the update. Next step is to import them.
