MATLAB Analysis Code window does not allow editing in Firefox 77.0.1

Firefox 77.0.1 does not allow editing in code window but Chrome Version 83.0.4103.116 works OK

Make a MATLAB Analysis to Send Email

1. First get your ThingSpeak Alerts API key from the Account > My Profile The alerts API key will start with ‘TAK’.
2. Create a new MATLAB analysis at Apps > MATLAB Analysis. Click the New button on the top. Choose the blank template and with this code. alert_body = 'This is the text that will be emailed';

alert_subject = 'This will be the subject of the email';

alert_api_key = 'YOUR_API_KEY_FROM_STEP_1';

alert_url= "https://api.thingspeak.com/alerts/send";

jsonmessage = sprintf(['{"subject": "%s", "body": "%s"}'], alert_subject,alert_body);

options = weboptions("HeaderFields", {'Thingspeak-Alerts-API-Key', alert_api_key; 'Content-Type','application/json'});

result = webwrite(alert_url, jsonmessage, options);

I just tried Firefox 77.0.1 and I don't have this problem. I suspect it is one of your plugins/extensions that is interfering with MATLAB Code window.

If you disable all your Firefox plugins, or try this in a Firefox Private Window (where plugins are disabled), do you still see this behavior?

I have tried Firefox Private Window and there is no edit capability. I have tried this after a restart of the MacOS 10.14.6

The same OS and Macmini8,1 running Chrome and Safari works fine.

Is the problem with FireFox?

[Vinod]

We tried a bunch of things and cannot seem to reproduce this in Firefox on Windows or older versions of Firefox on the Mac. I think the problem is related to this specific version of Firefox (77.0.1) on the Mac.
