We just upgraded to v126.96.36.1992 and it's working great in Chrome, IE and Edge. However, we're seeing a problem with Firefox ESR 52.5.3 and Firefox Quantum 57.0.4. You can log into the portal and open a new ticket or modify a new one. However, when you go to add text into any box or change one of the drop downs, it is very laggy for lack of a better term. It'll take 10-20 seconds for the text to appear in the text box if you start typing. The cursor doesn't show up in a text box or drop down field.
We've seen this on at least 4 separate machines. Everything works fine on older versions of Firefox (v38 and ESR v52.3.0 32-bit). We're just seeing the lag on Firefox ESR 52.5.3 and Firefox Quantum 57.0.4. Those are all the Firefox versions we've tested on. Anyone else seeing this?
