Restore backup fails when quiting Firefox with X

[dik23]

Description

When I restore a backup to a clean SmartProxy I see an error depending on how I close Firefox

If I close FF with the window's X in the top right the settings are borked

If I close FF with the exit option under the three line menu the settings are fine

Steps to Reproduce

To start "Factory reset" SmartProxy

Then backup / restore > restore backup > choose backup json

Restore completes. If I go to Smart Proxy then the profile name is Smart Proxy and all my settings are good

Close FF with the window's X in the top right

Reopen FF

The SmartProxy settings are missing and the profile name is {profile-name}

If I repeat this but use the Exit option from the menu rather than the window's X then the settings are there after restarting FF

Which browsers did you test this on?

Firefox

Affected browser versions

Firefox 127.0.2, Windows 11

Affected SmartProxy versions

SmartProxy 1.4.7

Screenshots of the problems or steps to reproduce

Settings restored:

Settings lost after FF restart with X

Firefox Exit - using this means the settings are good
