Using Waterfox here (don't recommend it btw, various bugs, will change back to Firefox in a few days as I'll reinstall Win10), no issue. Might have something to do with scripts : do you block anything ?
Yeah, I got it working, thanks. I just needed to close the tab and open a new one. I'd tried refreshing the page, going to different sites and coming back, etc... it just didn't occur to me to literally try a fresh tab.
