An errant setting on my backup program wrecked havoc on my FF profile. I have a backup from two weeks ago which I can go back to, but I'm trying to figure out how to get my browsing history from the past two weeks over to the restored profile.

Some options I thought about: and for clarity, the newer but bad profile is still loadable, I've mainly lost all my extension settings and stored data

• Is there any tool that would sync the entries from the newer/bad profile to the older/good profile?
• If I restore the older/good profile, would FF Sync just add back in the newer entries -- which presumably it has saved in it's system over the past two weeks?
• I believe the places.sqlite" file from the newer/bad profile is still intact. Should I just copy that to the older/bad profile?

I have to do a clean install of Windows, how do I save all my firefox bookmarks and passwords as well as Thunderbird addresses and any other info I might want to import back into Firefox and Thunderbird once I've installed windows again.

None of my saved passwords in my Mozilla account are showing up when I switch laptops and try to logon to various sites. Instead I have to manually enter the passwords for the sites every time even though the sites show that I have saved passwords for that site in my Mozilla account. When I type the password in a old or new site, Mozilla doesn't even ask if I want to save the password anymore.

I'm receiving this when I log on to Huffington Post. Never had this happen before. What's going on?

After the last update I can no longer see the comments section at the bottom of news articles on both Fox News and Yahoo. I double checked and they are workin fine on Chrome (I never this browser). I have been using FireFox for years and this is the first time this has happened. I am using Win 10 Any help would be appreciated Thank you

Hi there,

I know this is dumb, but I cleared my iMac's cache and nuked my entire history, password and bookmarks. This is catastrophic :( Can you please assist with any steps that may be able to allow me to recover this data? I have icould and it's synced, and I have a Firefox account but I cannot seem to find any way of restoring or accessing some backup. Please advise. Thank you!

Hello, I just wiped windows and lost my bookmarks, passwords, and the like. I looked into the support options, as well Firefox profiles (about:profiles) but can't seem to get that data back. It's odd to me that it didn't sync because I also wiped windows last month and it recovered all of my data as soon as I signed into my Firefox account,so I was hoping that would happen again.

Any way to get this back?

Thank you.

I thought that synchronization would save my data so that I could prepare my PC for reinstalling Windows. As a result, after all the procedures and installing the Browser, synchronization does not restore my data. It's very disappointing. And the history of old sessions is completely erased.

I have two computers. Both sign into the same Firefox account. Both instances of Firefox are the same version (134.0.1 64-bit).

On my main computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the first image (firefox_2025-01-19_17-42-57.png)

On the other computer, creating a new tab is set to Firefox Home (default), and clicking the "+" sign to create a new tab results in the recommendations appearing as seen in the second image (firefox_2025-01-19_17-43-57.png)

How to I get both instances of Firefox to do the same thing when creating a new tab, i.e. organize the recommendations like the second image?

I believe I had all this synced in Firefox Settings before I made the upgrade. Like all you fellow former users of Windows 10, I had to upgrade to Windows 11; and did so two days ago. Now, I found that I do not have under History any of the former sites I not only visited but also had tabs open. What can I do, if anything, to recover them? Under the Add-ons Manager, if this helps, I already had the app Tab Session Manager, but don't know how to use it. Thanks to all in advance who may have made this same upgrade. Many out there are still on Windows 10.

Hi, I’ve lost all of my saved passwords, bookmarks, and browsing history in Firefox. I’ve been a Firefox user for over five years, always tied to the same Firefox account email. My laptop recently had to be repaired, and the technicians performed a full reboot. After getting it back and reinstalling Firefox, all my data was gone. I tried recovering an old profile, but the reboot erased everything, so there are no old profiles or local data left on the device. Since my Firefox account has always been connected to the same email, I was hoping all of my data would still be recoverable, but I haven’t had any success. This represents over five years of saved information, and I really need help to restore it. Can Firefox support assist me in recovering my data through my account? Thanks in advance.

I know the system backs up bookmarks every day or so. I want to migrate all to a new PC. With a new Laptop it seems to have done so automatically, maybe through synchronize feature, I am not sure how I did that . I normally export bookmarks to a external flash drive as HTML. Just did also to a .json file type cannot find how to do that. Which format and method will be best? Have all of the old PC backed up through Acronis full back up. Will that have the full Firefox program with the bookmarks?

Dear Support Team

I hope this message finds you well.

I am reaching out to report an issue I am currently facing. I recently changed my device, and upon attempting to sync my Mozilla Firefox account on the new device, I noticed that all my data—including bookmarks and saved passwords—appears to be missing.

Please note that my previous device is no longer in my possession and has been formatted, so I no longer have access to the original data.

I would greatly appreciate your assistance in recovering my data and saved logins, as many of them are not stored in any other browser.

Thank you in advance for your kind support. I look forward to your response.

Best regards,

So recently I had reinstalled windows and reformated all my drives, I am also sure that this account is my only firefox account. But when i checked the sync data it shows only 1 sync data which is today 14/3/2025. I am also sure that I had left all my sync data as default therefore it should have automatically sync. But currently I do not have access to my bookmarks, etc
