I’m using Waterfox 126.96.36.199 for Linux.
The 3 buttons to the right of Recent Stories near the top of the front page of the site no longer change the layout persistently. If I select one of the non-default layouts, the layout changes. Then if I close my browser and relaunch it, the default layout appears again.
This isn’t a problem with Opera, Chrome or Firefox, only Waterfox. Since this appears to be specific to Waterfox, a fix may be needed in Waterfox. I’m asking where I should start looking to find the setting in order to report it to Waterfox.
