1730362 - Bookmark selection stepping

Status: RESOLVED DUPLICATE of bug 1724617

(Firefox :: Bookmarks & History, defect)

Description

[Don Buczynski]

Attachment: Firefox 2021-09-11 12.43 profile.json.gz

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

1. Open browser at https://www.google.com (not site specific)
2. Open bookmarks using Firefox menu 'Bookmarks' item. Approx 100 bookmarks/subfolders in top level.
3. Hover the mouse pointer over a bookmark entry so blue selection highlight appears.
4. Move mouse pointer to different bookmark entries.

Actual results:

The selection highlight steps, entry by entry, to the next hover point; at a variable rate but sometimes taking 1-2 seconds. More apparent when subfolders are involved in the step-over. Observed similar behavior in troubleshoot mode.

Profiler shows some mouse moves taking 15-25 ms. No Windows mouse related delay outside of Firefox.

Minimal delay in bookmarks usage.
