    Joni updated this article for fx66 March 8, 2019. The screenshot she added shows a More Information button. There's a bug to change the button text to "Advanced" but that hasn't happened yet. In any case, the instructions should match the screenshot so I'll approve the pending revision submitted today. Related bugs:

    Thanks.

    I replaced the Mac link with https://support.apple.com/HT203413 and removed the Windows links (I couldn't find any Microsoft links to replace them with). I also removed the Windows XP section since we no longer support XP.

    According to this article, a "Your Computer Clock is Wrong" error page is shown for various time-related error codes, including SEC_ERROR_EXPIRED_CERTIFICATE ...however, the https://expired.badssl.com/ test page produces a ""Warning: Potential Security Risk Ahead" error page with the error code SEC_ERROR_EXPIRED_CERTIFICATE and the error can be bypassed. I'll mention this in the contributors forum, https://support.mozilla.org/en-US/forums/contributors/713402 Firefox 66 for Desktop - Release Notes / Issues / Discussions

    I updated the article for fx66 to add a note about the "Your Computer Clock is Wrong" error page:

    There's a bug to change the button text to "Advanced" but that hasn't happened yet. <snip> Bug 1534629 Non-bypassable cert error pages should use "Advanced" instead of "More information"

    This bug has been fixed and the "Your Computer Clock is Wrong" error you get when you set the clock back now has an "Advanced" button in Firefox 67 Beta 4.

    I have a revision pending to update the article for fx67 along with a few other edits.

    I have a revision pending to update the note for fx66+ to add the "Did Not Connect" error with a link to the Secure connection failed and Firefox did not connect article.

    P.S. I approved my pending revision but didn't yet mark it RFL. I also think another revision is needed to consolidate {for fx66} and {for not fx66} sections for content that's exactly the same (such as the "Set your system clock to the correct time" instructions). I set a "Needs change" entry.
