HighSierra 10.13 with Java v8.211

The plug-in architecture is no longer supported by any of those three browsers. You can buy anything to your heart's content, but it is not going to make the plug-in work.

Both of those articles point to using web start applications. Whatever you need that requires a web browser, contact their support and see if they have a web start version.

Seems as of Safari 12, the plug-ins are no longer supported.

As for Firefox, you'll need to find an old, 32-bit version which will no longer work on Catalina being released this fall.

It doesn't matter what version of Java you install. The plug-in architecture it uses is no longer supported on any of the three major browsers.

• macOS: Use the Waterfox browser. In May, 2019, this is the only macOS (11.12 Sierra or later) browser that runs both Proteopedia and FirstGlance in Jmol with Java. Permission dialogs for using Java are straightforward.

To instruct Proteopedia to use Java, add ?use=java to the end of the URL in the browser's address line. Details.

To instruct FirstGlance to use Java, add &java to the end of the URL in the browser's address line.

Chrome doesn't support the Java web applet plugin anymore. If you recently updated that (or downloaded the current version), that may be why it doesn't work.

I think you can run it in Safari, but I don't know about FireFox.

Hi Barney,

Thanks for the info. Then How about Safari or Firebox ? Tried those also and could not get it to work.

Is this the version you have?

Have the the Java v8 installed.

Tried it with Safari , tells me unsupported plugin.

I think you need the v6 I linked to.

Or how about any other browser to work with java applet.

If I have to purchase a application that is fine with us.

Would you know if I need to purchase from Java in order for it to work?

Or what is the new way to work.

I figured a temporary fix. Reverted Firefox to version prior to 52 and it worked.

But need a updated way.
