Can someone advise me on this?

I recently uninstalled and reinstalled Firefox from the Microsoft store and was wondering if my old bookmarks and passwords are saved as backups somewhere and if so where. Or if its deleted when I uninstalled the app.

My bookmarks toolbar shows but it is blank. I had 60+ bookmarks on it. Why did Firefox trash my bookmarks?

Why did Firefox force me to create a new profile? I can get to my old profile, but the bookmarks toolbar is blank. The bookmarks showed for a while, then the toolbar went blank. What gives?

I have had all kinds of problems with Firefox the past several years, and I am about ready to can Firefox and go with Edge and Chrome. In my opinion, Firefox is a piece of crap, and I am fed up with it. I already have Edge and Chrome, but mostly use them as a backup when Firefox doesn't work right.

Is there any hope Firefox will get better, or should I jump ship with the other rats fleeing this despicable piece of junk? I have been hanging onto Firefox, because I am familiar with it and used to like it, and have used it for over a decade. But my patience is growing thinner.

I have suddenly lost all my firefox data today.. after creating a new browser profile? I never bothered creating profiles and stuff when the update for that came and it seemed like Mozilla never forced me to create named profiles until today when I open it again after booting up and it suddenly asks me to make a profile for the browser and after I did I just saw that I lost everything, I have a firefox account that's sync to my mobile phone but I can't seem to sync it neither, my browsing history, bookmarks, and passwords are all gone and I've even checked the AppData/Roaming/Mozilla/Firefox folder for it and even the recycle bin but I can't seem to find a single trace of my data before firefox forced me to create a browsing profile for my computer. Hoping someone has a solution to this.

Normally Ctrl+Shift+T reopens the last tab I closed in that specific window, but after the most recent update it reopens the last tab I closed in /any/ window. Is this happening to anyone else?
