Steps to reproduce:

Open burger menu -> bookmarks -> Manage Bookmarks
Select one or more bookmarks in "Other Bookmarks" section
Either press Del or use right mouse click -> "Delete Bookmark"

Actual results:

Firefox crashes
After restart, the first selected bookmark is deleted

Expected results:

Firefox should not crash and all bookmarks should be deleted

Happens only to some bookmarks, some are ok to delete, no idea what property those bookmarks share

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.

sure, there are a couple of report ids (happened multple times), these are:
72459cb2-ebe3-9bc9-0252-9d0b015eb958
074248d1-dd86-f93d-34ee-1c2a80bbf522
67ccb6e7-3e61-7c63-2671-c230b5345748
44d57953-a327-1baf-bd46-a64638153801
76fb9c9b-d386-d631-1ea1-035617f22f5a

strange, when the crashes happend, I already clicked the 'send' report button at the crash popup.
Seemed though they were not submitted. In about:crashes those crashes were still under unsubmitted section. I have again submitted them, here are the respective report ids:
bp-ac05268d-1e72-4a13-9c6e-787ce0211204
bp-265f3798-c708-4745-aeeb-52cad0211204
bp-09e31365-3763-408a-a7f3-82c2f0211204
bp-08136ba8-aad4-4aeb-9874-8d85e0211204
bp-71c6baba-522f-4e43-9893-8afc80211204
Strange also, that the uuids change. Would be maybe better if only prefix bp- is added, so that one is able to refer the submitted crashes to the unsubmitted crashes.

also, would be nice if date crashes is still visible in the submitted crashes section, that would also ease referring

seemes to be duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1624384

Thank you for crash ids, it does indeed appear to be a duplicate of bug 1624384.
