User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

I was attempting to delete a couple of old bookmarks and Firefox crashed. I discovered that whenever I delete a bookmark from the Library window, Firefox crashes. This happens every single time, regardless of what the bookmark is of.

Actual results:

When I select "Delete Bookmark" from the context menu or press the delete key on the keyboard, Firefox crashes. When I restart, the bookmark appears to be successfully deleted, because it is no longer there.

(Also, Firefox does NOT crash when deleting bookmarks from the bookmarks toolbar.)

Expected results:

Firefox should not crash when deleting bookmarks.

I am using Firefox 95 on Fedora 35.

I should add that this happens in Troubleshoot Mode with all add-ons disabled as well.

The Bugbug bot thinks this bug should belong to the 'Firefox::Bookmarks & History' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Bug 1624384 should fix this crash.
