Firefox has the wrong time

more options

Firefox tabs are showing the wrong time. For example https://overwatchleague.com/en-us/schedule is 8 hours off. This is happening in Firefox on two different computers. I managed to fix this for about 5 minutes.

Hi Wafflehouse00, have you modified this preference to "true": privacy.resistFingerprinting One of its features is to set the browser time to UTC instead of local time, so computations done in pages by scripts will be starting from that value instead of your true time.

Turns out the duckduckgo extension was causing this to turn back on 5-10 min after turning it off

Whoa, that's annoying. Hopefully there's an easy workaround.
