Usernames and Passwords aren't autofilling.

All my passwords are updated, Firefox is updated, computer is updated, I've restarted both my PC and Firefox, and I've double-checked that all the username and passwords are saved to the most recent. Usually when I click the area where you'd enter your username or password, it would prompt you to click and have it autofill. Hasn't been happening at all for me. Sometimes if I right click it then it'll give me the option to select it but it rarely gives me that option. I've been manually entering both and there would be a chance it prompts to autofill at least the password. I'm not sure if I'm missing something or maybe overlooking an option? I do have everything switched on in settings for it to autofill on it's own but it still doesn't do it like it used to. Is there anything I might be overlooking or completely missing?
