Hello. I am in need to open www site of Swegon AHU unit which is built on java. I have two installed java versions, 1.8 (one of latest of this branch) and 1.6. Problem is the AHU site is not working with anything newer than 1.6. I can't find proper solution for opening site with version 1.6 without much issues or much asking from browser. I need version 1.8 of java for daily use, and 1.6 is only for mentioned device. I tried to disable java 1.8 in java control panel but it doesn't seem to have any influence. I try to open site in Firefox 52ESR because for my knowledge is it one of latest browser which supported java. The problem is, Firefox each time is asking me what version to select for each class which must be loaded, and these classes are many for one page. It makes working with AHU a pain in azz. Everything because java is out-of-date. I know it is, but I don't have any option - these devices are not mine, and I can't upgrade firmware on myself, and can't force customer to do this. And I don't even know if there is any upgrade for them. I looked in internet but didn't find anything suitable for my case. Is there anything I can do with java or firefox 52ESR settings to make this site works flawless? I set applet in Firefox to not asking when activate java, but it still nagging me with questions and requires confirmations. I can't bypass it. I tried to use Internet Explorer 11 but there it is even worse, because out-of-date java is not allowed to run, no matter what settings i made in application. Please help.
