Keyboard shortcut working differently in Firefox?

Thanks for your reply. I've learned that what I'm experiencing is the new Firefox extension. I'm used to the Classic behavior - hopefully it will go back to that since it is now an extra keystroke. I prefer Command \ to auto fill the credentials - and if the vault happens to be locked, the unlock screen automatically comes up. Now I have to look, see if the vault is locked and hit Command . to unlock it if necessary then hit Command \ . I'm not a big fan of extra unnecessary steps.
