I have a problem in that bookmarks seem to have completely stopped working for me. I am not an expert in today's IT though a very long time ago I was. I am 81 and have incurable cancer and am confined to my home in a chair. I use FF many hours a day and I have a very structured set of tens of thousands of bookmarks. I use FF on a Windows 7 laptop. I am a contributor to Mozilla. A couple of days ago I noticed that I could not save new bookmarks. I then checked and found that I could not backup my bookmarks as either json or html. I reinstalled FF but these problems are still there. Today I have tried looking at your support information. I looked at your troubleshooting information. I copied raw data to the clipboard and out it into a MS Word file. I put FF into troubleshoot mode. I cleared the startup cache, after which I could add new bookmarks but not save any backups. I then refreshed FF and of course I then lost the first draft of this message . The refresh took quite a long time to complete, but it did. Afterwards I can still not use bookmarks. If I add a subfolder into them, I complete the process, the subfolder is added, but if I then sort the fold so that the subfolder is in place, nothing happens. If I go through the motions of backing them up, nothing happens. I see the following options open to me: 1 Buy a Windows 11 laptop, which I’m not keen on, and run FF on that. I have a windows 10 desktop available in another room, but I have no wish to be on the slippery downslope to eternally paying Microsoft for my computing. 2 Try and revert to an earlier version of Firefox. 3 Move to another browser, though for this and option 1, how to migrate my current set of bookmarks is an outstanding issue. I would greatly appreciate advice on how to get a functioning Firefox version back on my laptop. Yours, Jon

I perform backups to both HTML and JSON every day from Bookmarks > Manage Bookmarks in Firefox Windows. I noticed some bookmarks missing yesterday and so i went to restore from the HTML first. It did NOT restore all bookmarks that I had on my Bookmarks Toolbar. I then tried using the JSON file. Same problem.

Does that export to HTML or JSON not backup everything?

How do I copy files such as the 'bookmarkbackups' files from the Profiles folder?

As seen in the prtscr I get an error message when I try to copy any file from Profiles folder. Firefox is closed and I am admin and trying to copy the file as an adminstrator.

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).

I requested my Pocket export three times in June '25 and have received nothing. (Most recent request on 24th June '25, ID: 25174602-3e81-421e-a30d-71ff91dd2d66

I have also contacted Mozilla Support using the contact form twice to raise this issue and didn't receive any confirmation of those support requests to my email address.

The only possible explanation that I can think of is that maybe there has been a problem at the time when Mozilla acquired Pocket and I linked my Pocket account with my Mozilla account. I had previously used a different email address for my Pocket account prior to 2017. I currently have two email addresses (primary and secondary) associated with my Mozilla account but none of these email addresses are showing up in my Pocket settings, only my username. My Mozilla account is the only place where I can see my email addresses listed in my account details but I can't understand why I didn't get the confirmation emails to my Mozilla Support requests.

I used Pocket extensively for work so I really need to get the export. I'd really appreciate some help, thank you.

I am trying to create a backup of FireFox for moving from a Windows 10 machine to a new Windows 11 machine. The instructions for creating a backup don't make any sense.

--- Click the main menu, and go to Settings. Select Sync. Scroll down to Backup, and click Manage backup. Choose the location to save the backup file. ---

When I click the Main Menu, go to Settings, Select Sync, there is no Backup listed. If I search for the term "Backup", this is the result: "Sorry! There are no results in Settings for “backup”. Need help? Visit Firefox Support".

Syncing is on, so I am assuming that FireFox is being backup?? Or am I missing something somewhere?

When having restarted my computer and Firefox Nightly after a sudden power outage, all my tabs were gone. I need to restore them.

I went into the profile folder, but there was no session store file. Inside the backup sub folder i saw two large files, "previous.jsonlz4" and "restore.jsonlz4", and made a copy of both and placed them inside a new sub folder that I made, inside that profile folder.

An expert from the "Tech Support Guy" website ("Nader") told me, to open "about:support" and there to use the "Refresh" feature. I did this, but no tabs were restored. So I went into the profile folder again, just to see that it had disappeared and been replaced by a new profile folder! And therefore my two copies of the PREVIOS and RESTORE json files were gone, too, as they were inside a sub folder within that disappeared profile folder!

Now I need to know, URGENTLY, how to restore that folder and the files and sub folders within that profile folder. 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?

I'm changing computers. I want to upload my browser's bookmarks to a file. Then I can clear it for the next person to start from scratch. So far, I can't find a tab to make it happen. Please help. Thanks.

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.

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
