Hello,
The logout problem has been reported on 2024.4.1 but seems to be worse on 2024.4.2: Firefox Bitwarden extensions constantly logging me out · Issue #8873 · bitwarden/clients · GitHub (also https://community.bitwarden.com/t/bitwarden-firefox-extension-keeps-logging-out )
The endless spinner problem started with 2024.4.2: Endless Loading Spinner - Firefox Extension · Issue #9253 · bitwarden/clients · GitHub
I am on 2024.4.1 with FF 115ESR, with timed lock, and I don’t get locked out at all.
