New sessions don't save and can't save manually

[pmsobrado]

Short description

I'm gettings failed to save session whenever I tried to save manually. Also, the last automatic sessions saved seems to be from weeks ago, there no recent sessions saved. I tried uninstalling and reinstalling.

Steps to reproduce

1. Just try to save manually or wait for automatically save to trigger and see how it does not save anything.

Expected result

Sessions should be save manually and automatically.

Actual result

Failed to save session red message (I can't take screenshots) and no recent sessions automatically saved.

Platform information

• Platform (OS): Ubuntu 18.04
• Version of browser: 113.0.2 (for some reason Ubuntu 18.04 has stopped on this version)
• Version of Tab Session Manager: 7.0.1

More info: 7.0.0 version also fails, but latest 6.x does not. So I suspect some change does not work well with my FF/Ubuntu, or with the combination of FF and Ubuntu.
