The problem is that when I try to "join a game" and select search parameters, the "Process Games at Weekends" setting always gets set to "NO". Thus no games are displayed. This only happens with Firefox (V67.0.4) and started around the time the WIA was implemented.
I've hesitated to report this for a while as I thought it was my browser's cookies, but now I'm sure its not that. I say this because it also happens on my Android running Firefox.
It does NOT happen when running MS-Edge nor IE nor Chrome on my laptop
It does NOT happen when running Chrome on my Android.
I had a "saved search" set on Firefox. I have cleared my cookies. I set "Fog" and "Active" games and press "Search". The returned result is No Games and "Process Games at Weekends Only" is set which is why it returned no games. (See screen attached). The Search request changed my paramters

My guess is that my search parameeters must be saved on the system and not in cookies and something is working properly or else a bug in Firefox?
Oh well, just my 2 cents. I hope I've explained it well enough.
Thanks,
