The extension no longer activates automatically after a normal Firefox 148
restart. The extension appears installed and enabled, but its background functionality does not run until I manually toggle it off and on. This behavior is consistent and reproducible.

Steps to reproduce:

Restart Firefox (without applying an update).
Observe that the extension is present but inactive — no tabs are saved, and background features do not run.
Manually toggle it off/on in the Add-ons Manager.
the extension resumes normal behavior.


Expected behavior:
The extension should initialize automatically after a browser restart and resume its background functionality without requiring manual intervention.

Observed behavior:
After restart, the extension is inert until manually reloaded.

Environment:

Firefox version: 148 (64-bit)
OS: W11
Extension version: 2.0.1
