Java plugins are very much ancient technology. You should contact Cogeco to complain that they are putting you at risk by forcing you to use an old plugin that isn't supported by modern browsers

Thanks. I will.  :)

I use Cogeco webmail and since they use Java, I can no longer access my webmail (as of this morning). There is no option to "allow Java". I just can't log in to my webmail from the Cogeco website. The login page won't load (although the main Cogeco page loads fine). It's inconvenient to have to use Internet Explorer.

If the NPAPI Java Plugin from Oracle was indeed needed then it would be mentioned in say https://www.cogeco.ca/web/on/en/residential/support/131/125/faq-internet/email/webmail/what-is-cogeco-webmail

Access your emails securely whenever you want, with any device that's connected to the Internet

Only IE and Firefox 52 ESR (32-bit on Windows) even allows other NPAPI Plugins like Java to run. The Java Plugin is not available for Android or iOS devices for example. https://support.mozilla.org/en-US/kb/npapi-plugins

Even Chrome (since 45 version), Chromium (and Opera) has dropped support of all NPAPI Plugins which includes Java back in September 2015. So basically less reasons for websites to still make use of the vulnerable NPAPI Java Plugin.

Even Oracle is depreciating their vulnerable Java Plugin as it is only in Java 8 and not Java 9.

And just to be certain the NPAPI Java Plugin from Oracle and the JavaScript in Firefox are two separate things. JavaScript was originally going to be called LiveScript which would have eliminated the confusion but Java was the "in thing" back then at the time. http://kb.mozillazine.org/JavaScript_is_not_Java

No problem here with loading the login page.
