Firefox Community Forum

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

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.

Does ‘Firefox’ automatically send extra ‘backup authentication code’ once I use up the current lot it sent?? If not, what does 1 do for extra extra ‘backup authentication codes’ ??

I am unable to follow instructions for activating Backup in Firefox. I don't even have a Manage Backup button. What I have in its place is:

Backup

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

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.

When my Mac got an automatic system upgrade to 15.1.1 I lost everything. I was able to recover all my files but I lost the foxfire bookmarks and bookmark bar. How can I recover them?

Is there anyplace that shows how to use what the new release says on the 146.0. I got the message below when viewing new options in 146.0, but going to settings, sync just wants me to sign in and do a cloud backup.

Doesn't sound like what is in message below that I got after updating to 146.0. From what I found looking around, you are suppose to go to setting, sync, click on backup and choose location. There is no option backup, just an option to sign on. Below is message I got when checking what is in update 146.0:

Windows 10 users can now automatically protect their passwords, bookmarks, and more by turning on backup in Firefox. Your browsing data is saved daily on your device and can be encrypted with a password When you set up a fresh install of Firefox on any operating system for a new device or your current one, you can restore from this backup and pick up right where you left off. This feature is currently available on Windows devices and will be coming to other operating systems soon.

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?

I have Firefox installed on a Windows 11 desktop. The profile is missing, yet Firefox is working fine, and I see all of my bookmarks, etc.

I have windows set to show hidden files.

When I try to run %APPDATA%\Mozilla\Firefox\Profiles\ it tells me that the location is unavailable.

I cannot find the profile anywhere in file explorer, despite multiple tries to search for it.

If I go to Help > Troubleshooting Information, I see a "Location is not available" message, shown in the attached image.

I could uninstall and reinstall Firefox, but I'd prefer to solve this because the exact same thing is happening to my Thunderbird profile. It doesn't exist anywhere, yet I can see all of my emails and it appears to be working properly. I only found this problem because I wanted to backup my emails but was unable to.

Both of these profiles must exist somewhere, but I've tried everything to find them. Please help me fix this in Firefox, and then if I have a fix here I'll try to apply it to Thunderbird, where I have a lot of emails I'd hate to lose.

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!

Hello, I just tried to import bookmarks to Firefox, however they're not appearing on the title bar?

I imported bookmarks to desktop Firefox 134.0.1 (aarch64) on raspberrypios - 1.0, but the title bar only shows Import Bookmarks... and the imported bookmarks are located in Library -> All Bookmarks -> Bookmarks Toolbar/Bookmarks Menu -> Mozilla Firefox -> Imported Bookmark.

I am trying to export/import my book marks from one macOS computer to another (intel to Apple silicon), however, all of my imports and restore attempts fail. My last restore attempt failed with the following message: Firefox Unable to process the backup file. Any other suggestions?

Firefox update today 1-14-26 says Restore FF with a backup file" Instructions say go to Settings/Sync/Backup/Manage Backup. My Sync has no Backup option, only shows: Sync Manage account Device Name Syncing: ON You are syncing these items across all your connected devices: Bookmarks Open tabs Add-ons Settings Connect another device . How to proceed?

(I don't recall setting Syncing to "On" before; it also showed me as automatically logged in to my account.) Assistance appreciated! Thanks!
