Did you confirm what folder the file should be in? Please search for the file using your file browser.

The bookmark file is not there. Searched computer for "*bookmark*". Most recent file was from Feb 2015.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

Note:Open a file browser to that folder first, and watch it.

Opened in safe mode as directed. Saved bookmarks following these steps: https://support.mozilla.org/en-US/kb/export-bookmarks-internet-explorer. Bookmarks folder in My Documents is still empty.

(BTW: also solved the Flash Player issue you identified. Thanks!)

Bookmarks folder in My Documents is still empty.

Bookmarks are saved as an HTML file, not a folder.

When trying to save the bookmark file it goes into a folder also named bookmark. After trying to save the bookmark file, the bookmark folder is empty.

Let's try this. Save the HTML but place it on your desktop instead.

No, saving it to the desktop didn't work either. I saved a photo to the desktop this morning and that worked. I tried saving bookmarks there and there is no file newer than the photo.

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) 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. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory.

Do Not remove the profiles folder.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.

If there is a problem, start your Computer in safe mode and try again.

Followed the steps. After FF reinstalled, tried to save bookmarks to the bookmark file in an HTML format. The bookmark folder is still empty.

I've called for more help.

It's been nearly a month. I still have the problem: I cannot Export or backup my bookmarks so I can move them to another computer.

Is there anyone out there who can help me?
