bug: after Firefox crashes, groups and tabs sometimes do not restore (and other glitches occur)

[boldcompany]

After Firefox crashes, the usual process is that tabs (and Panorama Groups) open when the crash occurred are automatically restored upon restart of Firefox.

When using Tab Group Bar, this tends to not work as expected. Instead, often, upon restart of Firefox, only 1 of the previously-open tabs and groups is restored. When that tab is closed, several other tab groups open, but then many of the tabs are missing. Then, the Tab Group Bar functionality quits working (create tab, menus, etc.) and doesn't seem to work again until the add-on is uninstalled and reinstalled.

Any possibility of development on this?

Same for me.

I have backups scheduled three times per week. Before the backups run, it will kill Firefox to ensure no files are open and in use. When I start FireFox again in the morning, the tab groups bar is visible, but not functional. Adding a new group does nothing. The only way to fix it is to completely disable the extension, restart, re-enable, and restart once again.
