Browsing history reset itself unexpectedly

Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.
• I have checked that this issue cannot be reproduced on Mozilla Firefox.
• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

Hello,

My browser suddenly closed, and when I reopened it, all my open tabs disappeared. I had sync enabled, so I expected the tabs to be restored. My bookmarks were synced correctly, but my open tabs were not.

I want the tabs to return to their current state (April 15, 2025). I've sent screenshots and a video.

Expected behavior

I have a sync that is June 5, 2025 and I want my browser to be in that state. Because everything was in place at that time.

Actual behavior

All tabs disappeared, but sync was active.

Steps to reproduce

Unfortunately, I cannot provide exact steps to reproduce.
The browsing history was suddenly reset on its own and I lost all my data.

You can look in ... menu > history > recently closed windows to restore previous sessions.

I know that. Not all the history is there. I couldn't get back the sites I had opened over 400 times. At that time, when I formatted it, someone else accidentally deleted the data on my computer, and for some reason, my history was also deleted in Microsoft Edge. 😭😭😭
