Sidebery tabs will be blank/absent upon computer restart, and my custom tab groups will be lost

[Kelvets]

Steps to reproduce

Let me say that prior to this issue I had been using Sidebery for a few months without issues. I rarely restart the computer (because I prefer to hibernate it instead), but when I did restart it, I don't remember Sidebery having the issue I'm going to present now.

Let me also say that I used Firefox's "refresh" feature, reinstalled all extensions manually, and then disabled all extensions except for Sidebery, so the issue doesn't seem to be caused by an extension conflict or by some non-default Firefox configuration.

The issue: when I restart the machine and open Firefox again, the list of tabs on the side panel to the left will be totally absent/blank. If I then go to the Extensions section of Firefox settings and disable then re-enable Sidebery, all the tabs will show up again. However, the tab groups I had created (by this I mean the 35 and 17 tabs in the colored groups below):

will also be lost, will all the tabs from both colored groups falling into the first group (the one that has 29 tabs in the image above), making it have some ~80 tabs. Even if I restore a Sidebery snapshot to get the colored groups back, they will be gone again the next time I restart the machine.

I've tested with logging my Windows user off and then back in several times, and in all those times, Firefox opened with Sidebery working normally and with the colored groups intact. As soon as I restart the machine, though, the problem returns.

Actual behavior

Sidebery hides all my tabs until I toggle it off and back on, and then will have lost my custom tab groups.

Expected behavior

Sidebery opens normally, displaying all tabs and groups, whenever I open Firefox.
