I can see your source code, I do not think you are totally "safe from hacking" because I can go into your source code from my keyboard. It is a key combination on the Left hand side of the keyboard that opens the source code and the website layout.
Dude, what the... there are supposed to be ads there?
And you saw them using firefox!?!
Gyarrrg, do I need to scrutinize NoScript, ADBlock, or outside firefox in peerblock or my hosts file.
I'm too well protected, lol
This is what I am talking about. As you can see, there is a grid behind, and it seems like some kind of graphic arts program. There is some kind of code on the right hand side in the window.
I do not know too much about this, I just thought you knew that anyone could bring this up. I did not attempt to touch or move any controls, not knowing what would happen. It is different from the screen shot above because it has a grid.
I am running Windows 8.1 And I was browsing with Chrome.
You've accidentally opened the developer window in chrome by either clicking on the menu button, then tools, then developer tools or by pressing f12.
When a webpage loads, the server the website is hosted on will send the source code to your browser on your computer. Your browser will then interpret the code and build up the webpage that you're currently seeing. You can see this code by entering developer mode. Because this code is on your computer, any changes you make will be made locally and won't affect the source code hosted on the server.
