Ent Connect Problem

[BOcOPRO007]

So when i try to use ent connect in firefox,it closes the whole browser.
When i try to use ent connect in chrome,java(latest version) get crashed.
Can someone help me please?
----------------------------------
EDIT:
-The firefox thing is fixed by downloading a older version(v8u25) of java,i got the information from F-Train in chat.
-The chrome thing is still not fixed,still crashing.So u can still try to find the problem,because it could be useful for people who uses chrome.
----------------------------------
I'm done here,i don't need anymore the support,btw. Thanks F-Train for the info.
