How can I adjust the time in Firefox

Posted

My browser seems to have the wrong time. It shows Greenwich time, although I'm in Munich, Germany. How can I adjust this?

When resist fingerprinting (RFP) is enabled then some items are spoofed (TimeZone: UTC, UserAgent: Firefox 60 ESR on Windows 7).

You can check this pref on the about:config page to see if resist fingerprinting (RFP) is enabled and if this pref is user set (bold) reset to false via the right-click context menu.

  • privacy.resistFingerprinting = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

That should be based on your ISP and your O/S time clock that determines your time zone. If your using proxy or VPN that will give wrong time reading.

Hi MichaelTheHobbit, as WestEnd notes, Firefox will normally use your system time, and websites usually will "guess" your time zone based on your IP address.

Did you recently enable the privacy.resistFingerprinting preference? I think that tells websites you are in GMT instead of your actual time zone, but I haven't tested recently.

Bottom-Right corner on the Task Bar is the Windows-7 Time and Date. Click on that to change the time or Time Zone.

Hi all, thanks for your answers. The problem, however, seems to be of another kind. The O/S time clock setting is ok, but when I use our room planning tool, in Edge it shows the right time (Central Europe time), but in Firefox it shows one hour less. For me this means there's seemingly a separate clock in each browser. Because how else can Edge show it right when Firefox doesn't? Couldn't find a possibility to alter the clock in Firefox though, if there's one at all. Any ideas?

To check whether Firefox is reading your system time properly, could you try this:

Open Firefox's Web Console in the lower part of a tab using either:

  • "3-bar" menu button > Web Developer > Web Console
  • (menu bar) Tools > Web Developer > Web Console
  • (Windows) Ctrl+Shift+k

Then type or paste the following script next to the caret (») and press Enter to execute it:

new Date().toString();

The first time you use the console, Firefox may ask you to take action to confirm your understanding that it is dangerous to run scripts from strangers. (That is true.)
