1862551 - Firefox loses Workspace and Screen placements

Status: UNCONFIRMED

(Core :: Widget: Gtk, defect)

Description

[William]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0

Steps to reproduce:

• When I start firefox all the windows are displayed on the same Workspace (virtual desktop) and all windows are crowded on the same physical screen (monitor)

• This only began to happed with an update from late last week or this week which started Monday 30-Nov-2023

---

Firefox Developer 120.0b5 (64-bit)

Actual results:

• I have different Firefox profiles for different activities. E.g personal, development, business things, my daughter.

• Windows are normally displayed on certain windows based on the activity and need. So I can jump to the right desktop with one keystroke.

• Since the recent upgrade when I start Firefox fresh with a profile very often all or most of the windows open for that profile are showing on the same display.

This is a REGRESSION bug.

• Checking back this was reported fixed in: Firefox 75
  x https://bugzilla.mozilla.org/show_bug.cgi?id=372650

• Initially I moved windows to their correct Workspaces and Quit firefox, in the hope that it would save the location information after they windows are moved.
  x Unfortulately that didn't work.

• Am using KDE Plasma workspaces and activities. I mostly keep on profile to one activity -- Firefox seems to remain in the current activity.
  x I think that should be tested for too though because I do not use a profile across activities myself.

Expected results:

• Previously, before the recent update in the last 12 days or so, windows would be palced on the workspace and the same screen (monitor) they occupied the last time that Firefox Profile was active.

• We find this very convenient for keeping track of thing and being able to quickly go to check email or an invoice or homework, etc.

• Also there needs to be documentation on where the workspace, screen and activity placement of a Firefox window is remembered. Perhaps what would at least let me fix it manually, once.
  x For now it is a slow manual procedure to correctly dispense windows to their correct screen and workspace.

Remarkably like:

• https://bugzilla.mozilla.org/show_bug.cgi?id=1220675

This still happening with Firefox 121.0b4 on Kubuntu 23.04.

You're running wayland window protocol - it doesn't allow application to place itself on particular desktop or screen position. You'd need to use X11 for it (run with MOZ_ENABLE_WAYLAND=0 env variable).
