1684873 - Deleting history month-wise causes huge RAM usage

Status: RESOLVED DUPLICATE of bug 734643

(Firefox :: Bookmarks & History, defect)

Description

[Frederik]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:84.0) Gecko/20100101 Firefox/84.0

Steps to reproduce:

Opened the library to delete the browsing history. Selected all history older than 6 months, right click, delete.

System: Gentoo (precompiled binary), x64, X11
Firefox: 84.0.1

Actual results:

UI froze, firefox used all available RAM of the system (~3GB idle, 16GB installed), additional swap of 12GB got used. High CPU load. I closed the window after about 5min after starting the deletion process when I noticed the system load, RAM + CPU went back to normal. When I reopened firefox, the history was deleted / not visible anymore.

Same happened even with the monthly history, less RAM usage though.

Expected results:

Deletion of the history without such a heavy resource impact on the whole system.
