Constantly loses all tabs and groups on close: Librewolf RPM

[secretmango]

Describe the bug I have read very old other bugs (#1093 #1061) and this seems to be different.

To Reproduce I am on Librewolf 125.0.3 RPM on Fedora.

For some reason this did not happen on Librewolf Flatpak, at least not always?

every time I close the browser and reopen it, all tabs are gone. The extension has no groups anymore. But the backup location is the same, and the backup stays set at the 10min I use as a rough fix.

Expected behavior not losing stuff lol

Desktop (please complete the following information):

• OS and version: Fedora 40
• Firefox version: Librewolf 125.0.3-1 RPM
• Simple Tab Groups version: 5.2

Additional context I already went into the about:config and changed some settings and they stay set, not overwritten or something

privacy.clearOnShutdown.sessions false
privacy.clearOnShutdown.openWindows false
browser.sessionstore.restore_hidden_tabs true
browser.sessionstore.restore_pinned_tabs_on_demand true

some default settings that may be the cause

browser.sessionstore.persist_closed_tabs_between_sessions true
privacy.clearOnShutdown_v2.cache true
privacy.clearOnShutdown.offlineApps true

it still happens on EVERY restart

Help appreciated, this may be a Librewolf bug and it needs to be found and documented.

interesting, after adding privacy.clearOnShutdown.openWindows false now the tabs restore and the groups too, but the pinned tabs are gone

update: this did not persist, now they disappeared again.

I don't see how this is fundamentally different from #1035 or any of the linked related issues, unless you're completely losing the tab groups and not seeing them sitting at "0" tabs.
