All my sessions gone

[kngfbng]

UPDATE: It turns out that enabling "Always use private browsing mode" in Firefox's settings was causing issues, both with Tab Session Manager and otherwise. Disabling that setting brought the sessions back and made private windows/tabs behave as they should.

This "issue" can be deleted if desired.

Short description

I opened Firefox today and Tab Session Manager shows 0 sessions. I can't find a save file with the session list and didn't have backup option enabled. The extension won't auto or manually save new sessions.

Steps to reproduce

1. Start browser
2. Install Tab Session Manager
3. Have hundreds of sessions saved
4. Find out that all sessions are gone and Tab Session Manager won't work

Expected result

Find old sessions and save new sessions

Actual result

Tab Session Manager effectively stopped working

Platform information

• Platform (OS): Windows 10 Home
• Version of browser: 132.0.2 64 bits
• Version of Tab Session Manager: 7.0.1

Additional context

Firefox started acting out yesterday and seems weirder today: When a private window is opened, the address bar is not selected by default as it used to be; now pressing ctrl + shift + P opens a regular window instead of a private one and pressing ctrl + T from a private tab opens a regular tab instead of a private one. It appears that history is not being saved either. I've restarted Windows and the same issues persist. Bookmarks are being saved normally.
