Updated to version 65.0.1. All bookmarks erased when restarted and bookmark backups will not load, so how do I restore my bookmarks?

Posted

Updated to version 65.0.1. All bookmarks erased when restarted and bookmark backups will not load, so how do I restore my bookmarks?

Firefox upgraded to version 65.0.1 (32-bit) and when I reopened it after the upgrade, every bookmark on my Win10 PC has been erased.

Built up over 8 years of only ever using Firefox, there were a couple of thousand bookmarks. Following the upgrade, every single one of them has been deleted and even though I have a dozen or so backups listed as available to be restored but none of them work.

Instead of the expected restore, I receive this message when I try to load the backup file: Unable to process the backup file.

In other words, the latest update erased every bookmark from the sidebar, and despite there being a backup file, I cannot load it so I have now lost every site link I had saved, and there is no way to restore them because Firefox cannot read the backup file.

So the question is: Where can I find my bookmarks and how do I restore them?

If there is still a problem importing the bookmarks, Type about:support<enter> in the address bar. Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox. Locate the places.sqlite . Then rename or delete it. Restart Firefox. places.sqlite : History and Bookmarks. If the bookmarks still will not import, open the Bookmarks Manager and import the HTML file.

You, my friend, are a genius and I thank you for your help. Firefox is now reinstalled and my Bookmarks have been fully restored.

Thank you.

http://kb.mozillazine.org/Unable_to_process_the_backup_file_-_Firefox

jscher2000 has a tool on his website to extract out your bookmarks and save them to an HTML-format bookmark export file. If you want to try it, here is the page:

https://www.jeffersonscher.com/res/bookbackreader.html

To open the bookmarkbackups folder in Finder, use the "Open in Finder" button in the first table on the Troubleshooting Information page, and double-click into bookmarkbackups where you should see several dated files. From there you can drag and drop onto the conversion tool.

To import the HTML file, see the steps in this article: Import Bookmarks from an HTML file.

Sometimes the bookmarks backup files get corrupted.

Every now and then, Open the Bookmarks Manager; Press the Alt or F10 key to bring up the toolbar, and select Bookmarks. Hot key is <Control> (Mac=<Command>) <Shift> B.

Once the window is open, at the top of the page, press the button labeled Import and Backup. Select Export Bookmarks To HTML, and follow the prompts and save it to a HTML file.

If you want, you can Copy the file to another computer/profile. Repeat the instructions above, BUT select Import Bookmarks From HTML.

Thanks for your advice.

The tool you suggested successfully recovered my Bookmarks from the backup file and enabled me to turn them into an HTML file.

I've also used the tool to run a repair on the original backup file, from which I've made a new JSON file.

From these files, I've tried to recover the Bookmarks into Firefox but unfortunately I still hit the same error with the JSON file, and when the HTML file is used, nothing is imported. This suggests my version of Firefox may also have become corrupted.

I'm going to do a reinstall and then try to re-import the files.

Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.
