ArcGis either won't load or takes hours
I use Arcgis quite a bit for property info and for the last several months, it either won't fully load or has constant freezes when doing anything. It also freezes other windows I have open and most the time when I shut down those windows and start FireFox again, my home screen (Start Page) won't load? I have to dump history/cookies and sometimes flush dns. I contacted ArcGis and they say it works fine on their end. So I suspect FireFox is the issue.
I downloaded the Opera browser last night and it has no problems with this site. I won't use chrome or edge.
Any help figuring out what's going on? I have changed no settings, no vpn, no private browsing either. It seems with each FireFox update, my issues get worse?
