FF 154.0 will not create a backup file. Trying to create an initial backup to my D: drive (2 TB Samsung 990 Pro M.2 Gen 4 NVMe SSD with 86% free space). WIN Pro 25H2 Operating system, Intel Core i7-14700K CPU; 64 GB DDR5 - 5600 MHz Corsair Vengeance DRAM.

No matter what I do I can't get the initial backup to complete even though the D:/Restore Firefox folder was created. I consistently get this message, “Hmm, there was a problem with the backup. Please try again in a few minutes.” The message result of browser.backup.backup-debug-info is:

{"lastBackupAttempt":1787153673,"errorCode":9,"lastRunStep":13}

I'm trying to use Firefox Backup and have it save my sensitive data, but every time I enter a password, even if it meets the requirements, I get an error banner: "Something went wrong. Please try again."

It's very frustrating that the error message is so unhelpful. I have no idea what went wrong, nor how to fix it -- just trying again results in the same thing.

What is happening? How do I fix it?

helloooo

i am experiencing an issue with firefox where backup (Firefox Backup) is not working since version 148.0

problem: - when I try to create a backup, i get the error: “Hmm, there was a problem with the backup. Please try again in a few minutes.”

what I have already tried: - enabled and disabled backup password - changed the backup folder/location - cleared browser cache - tested across multiple updates (issue persists)

- backup is enabled, but I cannot create one - the error occurs every time - restarting the browser and system did not help

My windows10 laptop was destroyed, but I was able to retrieve the hard drive with all data in tack. I am currently using a new laptop loaded with Windows 11. I've been trying to find the bookmarks on my old hard drive to copy on a usb to reload on my new laptop with no success. HELP

Hi, I recently had a situation where I closed my browser, and when I opened it back up all my tabs and entire session was gone. There was no option to restore via any of the common or traditional ways. This was honestly traumatizing because I've put so much work into the setup of my tabs/folders, etc., for work purposes. SO MUCH TO LOSE. I ended up finding a partial restore deep in the files on my computer, but it missed the past 6 weeks, which I could never recover.

I'm sure I'm not alone - I've seen many, many posts and people talking about this. I think it's extremely important for Mozilla to ensure that the option of restoring browser sessions remains a reliable one, as many people have important work info, etc.

MY QUESTION: Is there a way to manually set a restore point? In other words, I was able to find the files from the browser session, saved up until 6 weeks ago, but no later than that. So, it's clearly saving sessions somewhere... I'd think it would be easy to prompt it to save at that current point in time asking it to save. Anyone know if possible and how?

Thanks

I had to re-install Windows and so I downloaded Firefox again and logged in to my account. I had sync turned on with bookmarks enabled but it wasn't syncing my bookmarks to my computer. I double checked that these sync settings were enabled on the Firefox app on my phone and I tried syncing multiple times. It transferred my passwords and other data but not my bookmarks. So I logged out of Firefox on my computer and phone, then logged back in and synced them together only to find that Firefox deleted all my bookmarks from my account completely (now they don't show up on my phone either). I looked at the forums and saw that they make separate profiles that I could access with about:profiles so I opened that and only saw 2 profiles, neither of which have my bookmarks. Is there a way to recover these since Firefox deleted them out of no where?

When I open the Manage Bookmarks --> Import Bookmarks --> Browse I have no listed backups, even though I can see them in File Manager \AppData\Roaming\Mozilla\Firefox\Profiles\c4i4a2zg.default\bookmarkbackups folder. I have copied the JSON file from my laptop which has not lost them but cannot select a folder/file location to import them, same for doing it via a HTML file.

I am stuck, thinking I may have to uninstall and then reinstall Firefox and then sync again.

Hello, I want to travel my profile manually. And may automate it by my home computer which is a WebDAV server.

But I find a big folder "Roaming\Mozilla\Firefox\Profiles\fgrfgcgt.default-release\storage\default" It is 2.65G which is a bit big. I can exclude/delete it from my backup?

I read article at: [https://support.mozilla.org/en-US/kb/.../firefox-backup?as=u&utm_source=inproduct#w_create-a-firefox-backup-file]

But in my up-to-date (or updated) FireFox, the restore backup by file option is appearing BUT enable backup or backup to file option is NOT appearing (screenshot attached).
