Well "C:\Users\Your Name\AppData\Roaming\Opera Software\Opera Stable" only works for the stinking windows junk. I use something much more secure and never crashes, Ubuntu- Linux and I don't need no stink'n virus scanner slowing down every Internet connection. So I am looking for the equivalence directory for Opera 41.0 for Linux.
Tried ~/.config/opera/Extensions/killkgpjebkgoibonbcjalcmlakflaha/1.6.2_0/css/ext.css, but it wants to change back to the original saying the file is corrupt?
