Hey so I have this IP printer that uses some java-applet to get it's work done, yet as of a few days ago, firefox dropped all support for npapi plugins but flash, hence java is no longer supported.... They have claimed to release some new distribution that would have extended support for java users... yet apparently this doesn't work for me.... any idea how to solve this and allow java support by my browser?
There's no hope for applets in the long run.
As for Firefox 52, you can add plugin.load_flash_only:false in about:config.
Or you can install Firefox ESR 52 to postpone the problem a bit longer.
Firefox
Open the Firefox browser or restart it, if it is already running
From the Firefox menu, select Tools, then click the Add-ons option
In the Add-ons Manager window, select Plugins
Click Java (TM) Platform plugin (Windows) or Java Applet Plug-in (Mac OS X) to select it
Check that the option selected is Ask to Activate or Always
Activate or on older Firefox versions, click on the Enable button (if the button says Disable, Java is already enabled)

I am worried about this little problem: I am creating a mobile game in unity and I need java openJDK, but I cannot install it via unity hub, I have already installed open JDK on oracle website (but version 14, which is not compatible with unity - error message says), where can I download the right version winhout singing to oracle or paying it?
Or does anyone has a tip how to fix the hub installing issue?
I faced the same issue. Later I noticed that my antivirus is blocking installation. What you could do is, temporarily disable your antivirus and add Open JDK module from Unity hub. It will work. Don't forget to enable your antivirus after your installation completes.
On windows - right click your unity version folder (in my case C:\Program Files\Unity\Hub\Editor\2022.1.0f1\Editor) and uncheck read only then click apply. If this doesnt work,right click again ,go to security tab select ALL APPLICATION PACKAGES user and check Full control.
After updating to Safari Version 12.0, the Java Plug-in under Safari > Preferences... > Websites > Plug-ins is no longer listed and therefore Java Applets cannot be ran in unsafe mode. Is there a way to enable the Java Plug-in or to run Java Applets anyway (on macOS)?
Safari 12 no longer supports java. As someone mentioned on the apple discussion forums one of the workarounds is to switch to Firefox version v52.9ESR. It is important to (quickly) disable updates within the Firefox preferences or it will update to a newer version that also doesn't support Java. Worked for me.
Safari 12 removes support for running legacy NPAPI plug-ins other than Adobe Flash, according to: https://developer.apple.com/safari/whats-new/
When I try to install Java 9 support plugin for latest Eclipse Oxygen from Eclipse Marketplace it stops on "Calculating requirements and dependencies" step. I have completely fresh instance of Eclipse (JEE package) and both, Java 8 and 9 installed.
When I revealed "sleeping" taks in progress area I found that it stops on this step (marked with red rectangle):
I tried few suggestions found over internet:
Disable firewall (windows built in and on the router side) and windows defender
Disable "Contact all update sites... option from "Install new Software" window"
run eclipse with vm parameter -Djava.net.preferIPv4Stack=true
even tried to install this while running at Windows Safe Mode
Changed Preferences -> General -> Network connections settings
Install packages manually by "Install new software" window instead directly from MarketPlace
None of them helped so far. Furthermore, when entered given url into web browser window, I was able to download content.jar. This entry comes as software source only when I try to install Java 9 support. It was not present on the software sources list and enables automatically every time I retry plugin installation.
Has anyone faced similar problem and knows how to solve it? Am I missing something?
A partial solution to my problem was to disable apache http client, described here: Disable Apache HttpClient.
It allowed me to go forward and install any plugin from Marketplace (actually Java9 plugin was only just one of many due to that "corrupted" URL.
I would not treat that as a permanent solution, cause I still don't know why default configuration is not working properly, but I can move on.
due to space reasons, I have changed the directory (E: instead of C:) in which I installed Java JRE. However, my browsers do not seem to be able to find the Java plugin when I do this. I have tried this with multiple browers (Firefox, Opera) so I do not think it is browser specific.
Is there any other setting I need to change? I have kept the folder names the same. And I am using Windows 10.
I have checked "Configure Java" and Java is enabled. Clicking on "Update Java" in the Java Control Panel also shows me that it is the latest version.
How can I get Java to work in my browsers?
I started learning GWT and wrote a sample app in Eclipse. I then said "Run on server". It gave me a URL to open and I opened that in Chrome. I saw a prompt asking me to install the GWT Developer Plugin and gave me a link. But I don't see any button to "Install". Is this some cruel joke from Google? What am I supposed to do now? How do I run the app? Eclipse only gives me this link which in turn gives me a prompt to install the plugin which I can't. On Firefox, it says version 29 not supported. What the hell is going on?
GWT Developer Plugin isn't compatible to Firefox 27+. So it simply doesn't work with your FF 29.
The reason why it doesn't work anymore can be found in a post by Brian Slesinsky.
You have several options of how to work in the future:
Use FF 26 (this can cause potential security problems)
Use FF ESR version (currently based on FF 24) that is typically used by Companies
Use Super Dev Mode
Use Dev Mode with another supported browser (e.g. Internet Explorer) and test FF with a compiled version of your application only.
