Hi. so how is this a Firefox issue ? Is your system clock showing the right time and date ? Only thing can cause this is in Firefox would be copy/paste below to Address Bar and Enter about:config?filter=privacy.resistFingerprinting Which would give time in UTC as for turning it off................... set to TRUE I guess.

Or copy/paste about:studies into the address bar then Enter and take Check Mark out of Allow Firefox to Run Studies. Restart Firefox after.

I will mark the other question as a duplicate.

I have Windows 7 not Windows XP.

Your useragent in your More System Details on right of post is Mozilla/5.0 (Windows NT 5.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0

The NT 5.1 is for Windows XP.

If you really are using Windows 7 and not XP then there are a few possibilities. '

Either you or a useragent switcher extension modified the useragent. https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox

Perhaps you are running Firefox in Windows XP compatibility for some reason. Right-click the application shortcut or the application icon to open the menu. Click Properties from the menu that appears. Uncheck the Run this program in compatibility mode for ...

You have toggled the privacy.resistFingerprinting preference in about:config from the default as one of the things it does is shows as if you are using Firefox 52.0

Firefox 53.0 and later including 59.0.2 requires Windows, 7, 8 (8.1), 10.

I think that most likely is that you have Firefox 52.7.3 ESR, but run this version in Windows XP compatibility mode.

Any specific reason for that?

Check that you do not run Firefox in compatibility mode. You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• hold down the Shift key and left-click the Reload button
• press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• press "Command + Shift + R" (Mac)

Clear the cache and remove the Cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache:

• Options/Preferences -> Privacy & Security -> Cached Web Content: "Clear Now"

"Remove the Cookies" from websites that cause problems.

• Options/Preferences -> Privacy & Security -> "Use custom settings for history" -> cookies: "Show cookies"

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
• do NOT click the "Refresh Firefox" button on the Safe Mode start window
