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?

About one to 3 weeks after I switched from windows, Fire fox changed my browser, and I lost all of my data. I hate my new browser, I am so mad That I reported this to the FCC. I already view all Info. nothing helped.

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?

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)

Hello all, i have a bit off an off one. I had a usb keyboard plugged into my laptop and and it had something sitting on it, I forgot it was there. I was using the laptop normal, and usually i use the CTRL and wheel on my usb mouse to zoom. But because of whatever buttons where pressed.. IT DELETED TABS(quite a few!)more thank the recent closed tabs could handle... i tired to do the session restore thing but im not super tech savy and messed that up.. But i do still have a copy of the json file thingy, but the backup thing got over written.. can i still recover with the one copy. The instructions are not the easiest to understand. Please help, i dont research and its been hard gathering that information. Thanks and if you need any more info just let me know!

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?

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

Firefox completely changed overnight without notice and I have lost all my bookmarks and can't find out how to access TV channels that were easily available previously on my desktop. Trying to make sense of changes but struggling. Nothing that used to work for me is still available. I don't even recognise it. Might have to give up Firefox.
