I have managed to reproduce this issue in Win 10 and Ubuntu 20.04.3 LTS using the following steps: 1. Open Nightly v96.0a1 from 2021-11-12 2. Login with a sync account that has some data. 3. Go to about:config 4. Change the value of the pref browser.migration.version from 121 to 120 4. Go to about:preferences 5. Activate session restore 6. Close session 7. Reopen the same profile Expected Result: The session is restored properly. Actual Result: The session is lost and the pages are improperly displayed. I have also verified the fix using the same steps in the latest Nightly v97.0a1 from 2021-12-28 and Beta v96.0b9, as it does not appear to reproduce anymore. @Darkspirit: 1. I could not reproduce the main issue in Mac OS. Do you think it should also reproduce in Mac OS? 2. It appears as if it could be intermittent. Is that a possibility? 3. How do I force the browser.migration.version to stay as 120 by normal user behavior? @CosminS: I also could not reproduce the issue with the bookmarks sidebar. Can you verify whether the secondary issue is fixed in the latest builds?
