How to fix "The bookmarks and history system will not be functional"

On one of our machines, we get the message

> The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

According to the user, this started after we upgraded the machine to MacOS 10.14 Mojave. We already tried to

  • restart the computer
  • start Firefox in safe mode
  • reinstall Firefox
  • move places.sqlite to have Firefox create a new one
  • create a new profile
  • refresh Firefox
  • granted Firefox full disk access under "System Preferences - Security & Privacy - Privacy"

all without success. I even tried to open places.sqlite with sqlite3, but wasn't able to find any tables, despite the file being +500kb.

The integrity verification of the places database produced the following output:

Task: checkIntegrity - Unable to check places.sqlite integrity: Error: Could not open connection to /home/g001570/Library/Application Support/Firefox/Profiles/scuoog8q.default-1541591890759/places.sqlite: 2153971714

> Task: invalidateCaches - The task queue was cleared by an error in another task.

> Task: checkCoherence - The task queue was cleared by an error in another task.

> Task: expire - The task queue was cleared by an error in another task.

> Task: originFrecencyStats - The task queue was cleared by an error in another task.

> Task: vacuum - The task queue was cleared by an error in another task.

> Task: stats - The task queue was cleared by an error in another task.

> Task: _refreshUI - The task queue was cleared by an error in another task.

This error code (0x80630002) leads me to "NS_ERROR_STORAGE_IOERR". Is this a correct assumption?

I'm wondering whether there are ways to find the original error that caused Firefox to show this error message (like "could not open file xy"), or is there a debug log that can be used to get more information about this problem? What's also puzzling me is the fact that this error persists even with a new profile or a fresh install.

Any help or advice appreciated. Thanks in advance.
