Firefox: Opening Sessions With Multiple Windows Issues

[TheGodEmperor]

There are several issues recently where if you have multiple windows saved to a session it will only open the first one and not all of them. It used to be all of them.

If you try and open a session in new window it does nothing if you already have window open, Used to work.

If you do replace in current window in an empty window it will remove your existing window open. This also used to work where it wouldn't close the existing window and replace with the session's window, but now it does.

• Platform (OS): Windows 10
• Version of browser: Firefox 125.0.3 (
• Version of Tab Session Manager: Version 6.12.2

Having a similar issue when I click to open a session, it duplicates all of the tabs (pinned and unpinned).
