Up until yesterday I've been using Firefox ESR 52.1.0 (64-bit) in order to access a VPN I need for work, which requires a Java plugin. I'm also running Firefox Developer Edition 54.0a2 (2017-04-20) (64-bit).Yesterday I updated Java to 'Version 8 Update 131 (build 1.8.0_131-b11)', and I can longer use Java plugins on any version of Firefox, which means I can no longer access the VPN.
It was my understanding that The ESR versions of Firefox would continue to support Java through into 2018, but this has not been my experience.
Are there any specific issues with these versions of Firefox that prevent Java Plugins from working, or is this an issue with that version of Java itself?
I am prompted to download and install Java Plug - in 12.4.1. Is this safe to do? Chosen solution Depends. The legitimate java plug-in is safe to install, but some websites use fake pop-up windows to trick you into downloading software that isn't actually java. Download Java SE 8 Environment 8 1.8.11.12 for Mac. Fast downloads of the latest free software!
