Steps to reproduce:
- I normally starts my Firefox.
- The profile manager shows up.
- I select the last one I used and click "Start".
Firefox showed a tab telling me a new version had been installed. But my other tabs were not shown. Instead, Firefox's started to hang on. I only had a blank page and Windows (7) told me Firefox was not responding. I have waited 15 minutes before killing it.
When I tried to relaunch it, I was asked to restore my previous session.
All my tabs were listed correctly in the session restoration page. But when I clicked to restore them, Firefox hanged on once again (a single blank tab in a blank page, Windows saying it does not respond anymore).
I have tried to migrate my profile information to a new profile (create a new profile, copy my places.sqlite, sessionstore, etc). And the first launching worked. So, profile elements are not corrupted. But when I close Firefox and reopen it, it once again fails to restore my tabs (haning on, not responding anymore). I had not migrated nor reinstalled extensions yet. So, this is not about extensions.
I have also rolled back firefox to version 67.0.4, and opening everything worked correctly. In few seconds, I had all my tabs shown. For me, this is a bug with version 68.
BTW, I must indicate I have thousands of open tabs.
Firefox should restore and show all my tabs.
