Firefox Developer Edition vs Firefox Extension Unlock Settings

Wondering if anyone else has noticed this…when I use Firefox Developer Edition, I don’t have to re-enter my master password before I can use the extension every time I launch the application. When I use regular Firefox, I am locked out from the start & whenever I’m away from the computer for a bit. The browsers are almost identical but I can’t seem to figure out where/how this is configured. In case it’s relevant, the regular Firefox is designated as my ‘default’ browser (OSX Mojave). Any insight/shared experiences appreciated!

This started happening for me recently and I did recently try and then uninstall the developer edition of Firefox. I just manually set it to ask for passwords after Firefox is closed again. Not sure why it changed in the first place!
