===Alternatives===

'''Firefox''' is still [http://www.ghacks.net/2015/01/24/mozilla-adds-npapi-plug-in-sandbox-to-firefox/ supporting the NPAPI interface] required for Java, but has announced [https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/ it will stop doing so at the end of 2016], at least in the standard browser setup. The new '''64bit Firefox''' does not support Java at all.
'''Internet Explorer''' and '''Safari''' support Java. See below for details for each of these browsers.

<!--====Chrome in Windows====
* Copy and paste the [https://java.com/en/download/faq/chrome.xml following line] into the address slot in the top of the browser:
:<span style="font-size:150%"><tt>chrome://flags/#enable-npapi</tt></span>
* Click the '''Enable''' link for the '''Enable NPAPI''' configuration option.
* Click the '''Relaunch''' button that now appears at the bottom of the configuration page.
* Enter ''chrome://plugins'' in the address slot at the top.
* Find ''Java'' and make sure it is Enabled (a ''Disable'' option is visible when it is Enabled). It should '''not''' be necessary to check the box ''Always Allowed'' (possible security hazard).
* You may have to allow a security warning specific to each particular site. Instead of seeing the molecule, you may see this:

Look for this in the upper right corner of the Chrome browser window: [[Image:Chrome-plugin-blocked.png]]
<br>But it will disappear in a few seconds, becoming this: [[Image:Chrime-plugin-red-x.png]]
*Click on the <font color='red'>red X</font> to open a permission dialog:

*Check ''always allow'' for the current site, and click DONE.
*Reload the page.

====Firefox in Windows====
*Open the menu in the upper right corner (or the ''Tools'' menu). [[Image:Firefox-menu.png]]
* Click ''Add-ons''.
* Select ''Plug-ins'' in the column at left.
* Make sure ''Java'' is set to ''Ask to Activate'' (not "Never Activate").
* Go to a test Jmol Java applet page: [http://bioinformatics.org/firstglance/fgij/fg.htm?mol=1d66&JAVA 1d66 in Java in FirstGlance].
* Click the ''Allow'' button in a gray security dialog that appears. (With Java 1.7 in Windows XP, you may need to approve several permission dialogs.)
* Now you should see the molecule! (If you don't, try simply reloading the page.)

<!--====Chrome in OS X====
In November, 2014, Chrome Version 39 was released which, for the first time, worked with Java 7 in OS X. In April, 2015, '''Chrome Version 42''' was released, and the instructions below apply to this Version.

====Firefox in OS X====
With Firefox in the foreground, open the '''Tools''' pull-down menu from the menubar (top of your screen). Select '''Add-ons'''. Select Plug-ins at the left, then under '''Java''' set it to '''Ask To Activate'''. (''Always Activate'' is not a safe setting.)
Now when you go to a website that needs Jmol, you may need to OK up to four permission dialogs before Jmol is allowed to run. Some have checkboxes to remember your choice.
