Tab Session Manager not working since Firefox v124

[SimonCrouzet]

Short description

Since I got Firefox 124, Tab Session Manager is not working anymore. It opens properly but I constantly see 0 sessions. I can import previous sessions and the import goes fine, but still "0 sessions" displayed on the main panel.

Platform information

• Platform (OS): Windows 11 22631.3447
• Version of browser: 124.0.2
• Version of Tab Session Manager: 6.12.2

Additional context

JSON saved sessions from before the bug are still in my folder, no JSON saved after the bug

I can confirm. I use tab session manager all the time and since a few weeks ago now. When I save a session it only saves one at a time. So it always just shows the last saved session and the others are nowhere to be found. This doesn't happen on developer edition though, only for regular Firefox from what I can see.
