• Affected platforms: Windows 10x64 (only on one station)
• Unaffected platforms: Windows 11x64,Ubuntu 22.04, macOS 12

Steps to reproduce

1. Open the migration window and observe the browser console.

Expected result

• No errors are displayed and the migration window is opened almost instantly.

Actual result

• Multiple Error: Error(s) encountered during statement execution: database disk image is malformed errors and migration window takes some time to open.

Regression range

• Not a regression.

Additional notes

• Attached a screen recording.
• The errors are displayed only for the first time after the migration window is opened. Opening the migration window again in the same session will no longer display the errors. However, restarting Firefox will display the errors again but only for the first time.
• Note this happens on only one Windows 10 machine.

:atrif, if you think that's a regression, could you try to find a regression range using for example mozregression?

I don't know, if this relates to this issue but if extensions (browser.migrate.chrome.extensions.enabled:true) are enabled I am seeing these errors as well (see attachment).

Setting 116 as affected because bug 1840792 was uplifted.

Hmm... Unfortunately, it seems that the errors can reaper in the same session if the Preferences page is closed and reopened and the Migration window is opened again. The steps are:

1. Open the migration window and close it.
2. Click the Preferences page and open the browser console.3
3. Open the migration window again and observe the browser console.
