After I switch to dark mode, I make sire the “disable auto dark mode switching” is selected.
On a regular basis, when my browser restarts I lose the dark mode, and have to jump through multiple clicks to turn it back on.
I do not have my browsers synced between devices, I use Firefox for this site, however I do have McAfee set to wipe all browser data on a regular basis.
If the setting is stored in cookies, where, what value? (I looked and did not see it), I can script to set that value so it does not reset.
