"If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem." 

I dread the days where FF has an updated version of something for me to install.. because this issue ALWAYS rears its ugly head. I've been ignoring the updates since Feb and for very good reason because this time (138.01 or whatever) I'm unable to bypass these security certificate expired error codes that say: "If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem." I literally was able to access all these sites without issue until I downloaded your must have update. How is this fixed??? Should I just uninstall FF and go back to Brave? I'm so tired of dealing with this as a normal day to day, no coding/tech background, etc. internet user.
