Please restore the java plug-in to the 'allow' list rather than just blocking all java plugin lower than whatever firefox decides. Even if the plugin versions are not stable or secure, they may be necessary for certain web based applications to continue to function. Right now, we are unable to do any editing because the editor requires java 6. Firefox really should not be in the business of deciding what java plugins should be blocked. Advising, encouraging updates, yes, but not blocking. There is always a reason for folks to need to continue using older versions. Sometimes money is a factor, especially in today's economy. Thank you for considering this.

since installing javasetup8u111.exe [and getting "verified Java Version 8 update 111"], I can't get on several web sites. I use "my.yahoo" as home page and not getting the "Options" settings that are described in various "help" links. I tried "about:config" to see if javascript is enabled but got lost in the muck! Am I off-track by trying to get to "Options" via my home page? Should I be on something else? HELP!!!

Hello, so I work from home virtually for one of the largest call centers in the country that provides support for a variety of clients. For my client we need to use Java for our "chat" feature to communicate with our supervisor and other agents in the field and also to access the schedule to pick and release work shifts. I noticed that my speed in moving thru screens online was a bit slow so I went ahead and upgraded to the newest version of Firefox yesterday having no idea it wasn't compatible with Java. Now I can't communicate with my team or pick up or release shifts. So I am in a bit of a pickle. I need to uninstall and reinstall the previous version of Java. Not exactly sure what that was or how to do that. It feels like ages since I had to. Any suggestions would be appreciated.

Hi,

I need to use a german authority website in context with firefox (68.10.0esr) to transfer data to the authority. After putting in the data and choosing a ZIP file for upload, a app (java) should open. This is a governikus secure software to confirm my identity by using a card reader and a trustworthy ID card. But the java app doesn't start. I use java 8.251. I have removed all popup blockers. The versions I use are recomended by governikus. I tried this with the microsft IE11 as well, doesn't work ... Could the problem be java sript? I have to activate it but I don't know if it is activated and I don't know how to activate

I hope you deliver the solution ;-)

Regards

I am using Firefox and Java runtime latest versions. Firefox version is 46.0.1 and Java runtime version is Java8 Update 91. When I go to any site which uses Java plugin, Firefox shows a warning message saying that Plugin is vulnerable but when I see in the Firefox addons, it says that the plugin is up to date. I trust the site from where the .jnlp is being downloaded. My question is can I ignore the warning? Also why I see this warning when everything is up to date.

I have to access a legacy, Agency-wide software application that uses Java in its interface operations. The previous Firefox esr version allowed the activation of Java for trusted sites. Firefox 60.2 esr appears to have done away with this option . . . and best of all it installed itself without my intervention or choice. Now, I am locked out of our timekeeping software.
