Wrong Timezone in Firefox Browser

Hi there,

I've searched and tried all the solutions I could find, but my FF browser still shows my timezone as Central, which is two hours ahead of my timezone, Pacific. MS Edge displays correctly, it's just FF that has the issue. There are a couple of add-ins that say they can update the timezone in FF, but not sure if I should use them (not trusted).

I verified that privacy.resistFingerprinting is set on false. Also, my control panel timezone is correct and set as Pacific, but just to see if it would correct it, I changed it and did a restart, changed it again and did a restart, and FF is still displaying Central time.

Thanks in advance for your help...

Jim

Time zones are controlled by System O/S and timestamp zone is controlled by ISP well.

Thanks Dropa. My system O/S time is correct as Pacific. I would think that the ISP may be a possibility, except that MS Edge browser displays correctly for me on the web portal page where I need the time to be correct. Also, other local user's times are correct in FireFox.

So what site or link or how are you verifying your TZ on the Browser?

The timezone displays incorrectly in a private web portal (appointment times) using FF. Using Edge, the appointment times are correct.

Problem here is a private login sites makes figuring out what the issues in Firefox even harder to diagnosis.

At first I assumed it was the portal that had the issue, then they confirmed proper settings on their end. Also other user's TZ was displaying correctly in there using FF, and Edge displays correctly for me.

Current Pacific time is 12:59:55 PM. However, when I enter the following script into the FF Web Console - (new Date()).toLocaleString() Here is what it returns:

"6/20/2022, 2:59:55 PM"

What gives this longer version ?

  • (new Date()).toLocaleString("en-US",{weekday:"long",day:"numeric",month:"long",year:"numeric",hour:"numeric",minute:"numeric",second:"numeric",hour12:false,timeZoneName:"short"});

You can also check other timeZoneName choices like timeZoneName:"shortGeneric".

What timezone do you get if you paste this code in the Web Console ?

You should see the result without needing to press the Enter key.

  • (new Date()).toLocaleString("en-US",{timeZoneName:"long"});
  • (new Date()).toLocaleString("en-US",{timeZoneName:"short"});
  • (new Date()).toLocaleString("en-US",{timeZoneName:"shortGeneric"});
