Firefox Community Forum

I won't show my account information but when I try to access Amtrak's Guest Rewards site it goes into a loop. First it asks for username & password and accepts that with no problem. Then it asks for the code it sends to my cell phone and accepts that. And then it just keeps reloading various pages until I kill it. This is the error message shown in the log, it's repeated over and over:

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFaviconService.replaceFaviconDataFromDataURL]

   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:220
   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:647
   setIconFromLink resource:///actors/LinkHandlerParent.sys.mjs:139
   receiveMessage resource:///actors/LinkHandlerParent.sys.mjs:60

LinkHandlerParent.sys.mjs:148:17

I'm running under Mac OS 10.13.6 The site loads fine when I use Safari (version 13.1.2)

Thanks

Onshape starts ok and displays all page toolbars and the graphics correctly for around 3 to 7 seconds then it all goes blank for several seconds and then only the toolbars etc return. The graphics for the model disappears along with the camera view which shows where the model is in x y and z and also the camera does not move with the right mouse button pressed. See pics below:

L to R - Proof of model existing although not shown in work area

          - Additional proof of 2nd model not showing in work area
          - Actual screen after the display blanks and reappears

It also happens in all web pages but the data comes back, Onshape is the only cloud based App I am currently trying to use. I did install a Xerox print service recently and that needed a .NET update (3.5), after that these problems started. I have uninstalled and reinstalled Firefox from the Mozilla site which cured the problem at the time but it has since returned.
