Reinstalling Firefox with a fresh download does not resolve the issue
Removing all data does not resolve the issue (CleanMyMacX application reset)

Repeating to open and close Firefox will add more items to the dock

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for the report. This looks like a duplicate of bug 1827486 which happens when the Delete cookies and site data when Firefox is closed setting is enabled. A fix should be available via update soon. See bug 1827486 for details.
