All of my history except of today's has disappeared. I did not erase my history, and really need it back. I did try to remove a couple of sites from my Most Visited, as Firefox was saving all sorts of sites I don't really visit often. In addition, I am being asked to sign in with my password at every site I go to where as before I was automatically allowed to enter, as all my passwords are saved. What happened - and how can I get back to normal?

I am using Firefox 150.0 in Linux Mint Cinnamon on a Byte. I always turn off my computer when not in use. Recently I noticed that my search history has become very truncated. Specifically, if I use an in-site search function, my searches no longer appear in my browser history; I only see the address for the site's main page. If I want to resume a search after turning off the Byte, I have to navigate to the site main page and re-enter the search parameters, then try to remember how far down in the search results I got the last time.

I realize that I can bookmark searches. But the stuff I am doing may require returning to a parameter-heavy search that I did a month ago and didn't think I would need again.

Is there some way to adjust this new, uninformative default History dialog box and see my entire browsing history again?
