1555755 - Restore Previous Session is Broken in 67.0 ... it only remembers the leftmost 10 tabs

Status: UNCONFIRMED

(Firefox :: Session Restore, defect, P3)

Description

[myisland2001]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

I create 20 tabs and at end of the day I close Firefox and shutdown the PC and go to bed.

Note: I am using Windows 7 on a desktop PC. Firefox version 67 initially lost 100+ tabs. I still have my history and I can't afford to ever lose that.

Actual results:

The next day I startup my PC and open Firefox and it only remembers the first 10 tabs.

Expected results:

Firefox should have restored 20 tabs.

It's been 16 days and no action from you guys. Every day when I open browser I don't know how many of my tabs will be restored from previous session. Sometimes 3, sometimes 10 sometimes 20. Why is don't you fix this bug?

For me the "reload previous session" feature is broken completely in 67.0.1 -- I'm not even getting the leftmost 10 tabs.

I can not reproduce this issue, I'm afraid, so I need a bit more information to be able to see what the problem might.

Can you go into about:support and put its contents into a file and attach it to this bug? You can also use https://paste.mozilla.org/ to save it online.
I would also like to ask you to try to reproduce this in a fresh profile. You can read all about that over at https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

Thanks!

I haven't seen the problem since I installed Tab Session Manager to Firefox. The problem probably still exists had I not installed it. I don't have the time to set up the tests that you require me to run this Summer.
