You will need to download Java or update to the latest version to load Minecraft. You can verify your Java version here. Make sure your video card drivers are up to date as well, or you may encounter crashes or low quality graphics.
Java Security Exception Errors
Remember, only Internet Explorer and Safari can load Minecraft without issues. Chrome won't work at all. However, if you really want to use Firefox, follow the instructions below.
- Type in about:config in the address bar and press Enter. If prompted, click on I accept the risk!
- Right-click anywhere in the list and choose New then Boolean.
- Type in plugin.load_flash_only then set it to false and click Ok.
- Restart Firefox and it will detect Java and load Minecraft.
Your browser may automatically stop Java from running when Minecraft tries to load. Make sure you enable Java in your browser if it prompts you. If the problem persists and you have a security exception error, you may need to lower your Java security settings in the Java control panel (JCP). Follow the step(s) below for your operating system to get to the JCP.
- Press the button, type in configure java and press Enter.
Mac OS X (10.7.3 and above)
- Click on the icon.
- Go to System Preferences.
- Click on the Java icon.
Java Control Panel
Once you are in the JCP, take the steps below to ensure your security settings and browser allows Java to run successfully.
- Go to the Security tab and make sure Enable Java content in the browser is checked off.
- At the bottom you will see an Exception Site List. You will need to add three entries to this list, so click on Edit Site List… to begin.
- Click on Add and type in http://minecraftforfreex.com/. Then click on Add again. A popup will appear to confirm; just click on Continue.
- Do the previous step again, but type in file:/// instead. Yes, there are three slashes.
- Finally, type in http://s3.amazonaws.com. Please note the https at the beginning. Click OK to save these entries.
When you’re done, it should look like this image. If everything matches, click on OK.
Try to load Minecraft again and Java should ask if you are sure if you want to run an unsigned Java applet. Just keep clicking OK and the game should load fine.
