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 went to [https://support.mozilla.org/en-US/kb/firefox-backup] and under "Create a Firefox backup file" at step 3 it says, "Scroll down to Backup, and click Manage backup" but when I went there no such "Manage backup" option exists as you can see in the attached screen capture. So what gives? How can I "Create a Firefox backup file"? I am using Firefox v147.0 (64-bit) on Windows 11 Please instruct. Thanks RJB

I love my current Firefox settings, bookmarks, folders and color, background image, dark mode. All I want to do is to create a Firefox browser backup file. I don't want to restore or sync anything. I just want a backup file in case of computer failure to restore to my next computer if ever necessary. I'm using Windows 10. I think they used to be "json" files? The only "Backup" link in the menu only addresses Restoring from a file. I just want to create a backup file for this current browser just the way it is. Is there a simple solution? Thank you SO much!!

Hi,

On the "Your Firefox has updated" page, I recently found out that in addition to Firefox Sync, you can also create a backup in the form of a local file. When I try to follow the instructions on the support page for the function (here I get stuck. For some reason I am only allowed to choose a file to restore my data, but I am not allowed to create a new backup. I have tried refreshing Firefox and even creating a new profile, but both have the same issue. I am not seeing a "manage backup" button either (see screenshot).

It's not the end of the world thanks to Firefox Sync, but I would like to get it working as a nice backup :)

Thanks in advance for any help you guys can give me!

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).

If I go to the profile folder, exit firefox then copy and paste the folder to a backup location. The attempted backup fails. Something about permissions as I recall. I have tried many things unsuccessfully. Something has changed that does not allow for the backup of profile folders. Adding a backup option to the profile manager would be nice. I noticed some people have found work-arounds but I need a straight-forward procedure for backing up my folders. No work-arounds please, just a simple procedure. May I ask for help with this issue?

My Profile Folders can't be backed up. Messages I receive while attempting a backup state that permissions are required to backup certain files. I'm working in an administrator account so that shouldn't be an issue and I use to backup my Profile Folders without an issue.

After a problem with his Internet connection, a friend is now unable to open Firefox. At first the message was that ‘… this tag has crashed.’ Now the message is that it cannot find something with a .dll at the end. I suggested to simply uninstall and then reinstall Firefox, which would also ensure that he has the latest version. However, he has no backup of his bookmarks.

I was, therefore, wondering whether it is possible to access the bookmarks somewhere else on the computer, in order to back them up before the uninstall/reinstall procedure.

Many thanks.

Hello:

I am trying to create a csv file of my passwords to import to Microsoft Edge from FF. I went through these steps in Firefox:

Settings>General>Import>Select Passwords from CSV...

...and then it takes me to browse my computer for a CSV file that I have YET to create. I don't think this is how you create such a file.

I'm not sure how to import my passwords to create a CSV file so I can put them into MS Edge. When I tried importing my password (and all my other data) inside of Edge via Edge, it only brought in 235 passwords from Firefox where I have 422. So I would assume if I used and imported my passwords to Edge via a CSV file instead that all my passwords would populate in Edge not roughly half of them.

Could you please tell me how to create a password CSV file in Firefox to use in Edge?

Many thanks in adabce

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?
