Sometime between 10PM 7/23 and 2 AM 7/24 I deleted my profile by mistake, and all of the data my browser collected has been lost. Passwords, history, cookies, chat logs, etc. No account sync, or official Mozilla profile until now.

Everything is gone and I don't know how to replicate the steps found in this video. Mac's don't conveniently show you things like deleted user data unless you know exactly where to find them. [|https://youtu.be/JWJwmKLqnZs?si=g_g47eHSwoB8XSL5]

I've already tried using Time Machine, but that failed spectacularly.

Current OS is macOS Tahoe 26.5.2, Firefox 153.0 (aarch64)

After the last few updates I have lost all of my bookmarks, I don't understand how this could happen. The bookmarks that currently populate my side bar are either inaccurate or empty. I'm flummoxed and frustrated and angry. Is it possible to recover past bookmarks - say a specific date?

After closing the records in the window, how many windows can be kept now?

I had 6 windows open before closing my browser, but only 5 were automatically restored after reopening it; there are no other windows in the closing history either. What happened? There are no other windows in the closed history section either. What's going on!?!?

I spent almost an entire day setting up my firefox browser shortcuts, themes and extensions on my laptop. It was exactly how I wanted it. Now it is all gone! I had not written all the web addresses down. how do I get them all back?

Hello, I am requesting assistance recovering my original Firefox profile. My original Firefox installation unexpectedly disappeared from my computer. Believing I needed to reinstall it, I accidentally downloaded Firefox from the wrong source. I was eventually able to recover my Firefox profile, but Firefox repeatedly crashed afterward. To resolve the crashes, I uninstalled Firefox and then downloaded the correct version from Mozilla's website. After installing the correct version, my original Firefox profile is now completely gone. Before this happened, my Firefox profile contained all of my saved passwords, bookmarks, browsing history, and folders, including important folders such as Bills and Jennifer. Those folders are no longer present. I would like to know whether there is any way to recover my original Firefox profile or restore the missing data. If there are any recovery methods or diagnostic steps you can provide, I would greatly appreciate your assistance. Thank you for your time. Sincerely, Jennifer Harbaugh

I had many work tabs open when I left the office yesterday. The update that occurred overnight closed and erased my current window, and now the "restore previous session" option is not available. These were collected over months, so the general 'history' page is not helpful in this instance. How can I restore my previous session and get all my open tabs back that I had yesterday?

I have tried restoring my bookmarks using these steps but it doesn't work. Specifically, when I try to select "Choose File" in Step 3 nothing happens. The option will highlight, but when I click on it no window to choose a file pops up. Is there any other way to restore bookmarks using a json backup?

My bookmarks list has inexplicably disappeared. It might be related to the fact that I briefly switched to Google Chrome to connect to a Facebook Zoom meeting – although I've done this several times before without any problems. So, what can I do to get my bookmarks list to reappear? I hope it's not too complicated! Thank you for your advice!

Both user accounts on my work pc have no passwords from shutting my pc off on friday and coming in on monday. no errors otherwise. all my bookmarks and tabs are still there but no passwords. I see a logins.json-15.corrupt file from friday. If i change the name to logins.json and try to open in firefox it says "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data"

What else can I try to recover my passwords? I don't have it synced.

What the hell has happened to the support environment? I've tried to resolve two big issues recently, and I can't find anything of value. I've lost the ability to pin an extension to the toolbar after losing my entire profile on this computer, tabs and all, using Tab Manager. I can't find a way to recover the profile, so I've given up on that. Now I can't get my most-used extensions back on the toolbar.
