Firefox launch opens /home/pdl/Documents/Browsers/Firefox/chrome as a new tab, I have set the setting "Open previous windows and tabs" on and off, I prefer this setting to be enabled, my OS is LMDE 6 and Firefox is the flatpak install version 137.0.2 (64-bit), I have also tried the system install and deleted all Firefox in between installs or should I say I think I did, please this is driving me nuts, even with me logged out of Sync this happens.

Thanks
