I can only access this forum via current Edge which works extremely fast here. On my default browser Basilisk (forked off Fx 52 ESR) I get Access Denied here and the same thing occurs with Fx 60.9 ESR (that I use because some of my extensions won't work right on current Fx ESR version). I have a friend in IT who thinks the Access Denied error may be from Akamai which could be except I can post here using current Edge on Windows 10 ver 2004.

On my iPhone XR, I have Fx Daylight as my default browser and am not having problems accessing retail store websites.

I appreciate the response from web but still don’t know why Firefox is being blocked from retail sites.
